How it works

Call forwarding for a shop phone - and the part it does not fix

The short answer

Call forwarding sends calls that come into one number out to another number instead. On a shop line it is almost always a free feature you already have, it takes about thirty seconds to turn on, and if your shop phone currently rings in an empty office while you are on a roof, you should go turn it on today.

What it does is move where the phone rings. What it does not do is make somebody free to answer it. If you are under a truck with both hands busy, a call forwarded to your pocket is still a call you cannot take - it just rings closer to you before it goes unanswered. That distinction is the whole point of this page, and it is the thing nobody tells you when they suggest forwarding as the fix.

What call forwarding actually is

It is a feature of the phone line itself, not an app or a service you sign up for. Your carrier - whoever bills you for the shop number, whether that is a mobile carrier or the company that runs your landline - handles the redirect on their end. The caller dials your shop number exactly as they always have. Your carrier sends that call to whatever number you told it to.

That means a few useful things. You keep the number on the truck, the yard sign and the Google listing. The customer never sees a different number and never has to learn one. Nothing gets installed on anybody's phone. And on most plans there is nothing extra to pay for the feature itself - Verizon's own call forwarding page says there is "no monthly fee for Call Forwarding on most plans."

The three kinds, and why the difference matters

This is the part most shops never find out about, and it is the difference between forwarding being useful and forwarding being annoying. Carriers publish more than one kind, and they behave completely differently.

The codes below are the ones AT&T publishes on its small-business support pages and the ones Verizon publishes on its call forwarding page. They are examples, not a universal standard - landline carriers, cable phone providers and mobile carriers all differ, so get the exact sequence from whoever bills you for the line. The useful thing here is not the digits, it is knowing which of the three to ask for.

  • Forward every call: Everything goes straight to the other number and your shop phone never rings at all. AT&T publishes "Press *72, enter a forwarding number, and then press #" to turn it on and "*73#" to turn it off; Verizon publishes *72 plus the 10-digit number, and *73 to turn all forwarding off. This is the right setting when the shop is closed or nobody is there - and the wrong one if anybody is still sitting at that desk.
  • Forward only the calls you do not answer: The phone rings where it normally rings first. If nobody picks up within a few rings, the call rolls out to your cell instead of to voicemail. AT&T publishes this as No Answer Call Forwarding - "Press *92, enter a forwarding number, and then press #," and "*93#" to cancel. Verizon describes *71 as the way to "forward only the calls you don't answer on your mobile phone." For most shops this is the one you actually want, and it is the one almost nobody has set up.
  • Forward only when the line is busy: The caller who would have gotten a busy signal or call waiting gets sent somewhere else instead. AT&T publishes Busy Call Forwarding as "Press *90, enter a forwarding number, and then press #," with "*91#" to cancel. Worth having if you are a one-line shop and a second caller currently gets nothing.

What it costs

The feature is usually free. The calls may not be, and this is the part that surprises people.

Verizon states it plainly: "If you don't have unlimited minutes, you'll be billed for all forwarded calls according to your plan. You'll be billed just like you would if you answered the call from your mobile phone." In other words the forwarded leg is a call, and a call uses whatever a call uses on your plan. On an unlimited plan that is nothing. On a metered line it is not.

Ask your own carrier two questions before you lean on this: is there a monthly charge for the feature, and does a forwarded call consume anything when it rings through. Those two answers are the entire cost picture, and both are things your carrier publishes or will tell you.

The limits carriers publish

There are a handful of restrictions worth knowing before you set this up, because they are the ones that make a forward silently fail.

Verizon lists the requirements for the destination number: it has to be "An active voice-capable line," it has to be "In the US," and it has to be "10 digits long (area code must always be included)." It also says plainly that "Calls can't be forwarded to an international number." A number that is data-only, or an extension, or a number you typed without the area code, will not work.

AT&T adds a detail worth knowing about activation: after you enter the forwarding number, "the system will automatically place a call to the number to which calls will be forwarded," and somebody has to answer that test call for the forward to take. If you set this up from the shop phone while your cell is in the truck, it may not stick. Have the destination phone in your hand.

Forwarding a business landline to your cell

This is the most common version of the question, and the answer is usually yes - a landline or cable phone line can forward to a mobile number the same way, you just get the code from that provider rather than from a mobile carrier. It is the single highest-value thirty seconds an owner-operator with a landline can spend, because that is the line that currently rings in an empty building.

Two things to sort out while you are in there. First, the landline is almost certainly not text-enabled, so a customer who gives up on calling and texts that number is sending it into a void - that is a separate fix, and our guide on texting a business landline covers what it takes. Second, once calls land on your cell, your cell's voicemail becomes part of your business, which means the greeting on it is now a business greeting. Most people never change it, and the customer hears a personal outgoing message on what they think is a professional call.

Test it before you rely on it

Carriers are inconsistent about documenting what happens after the forward, so rather than take anybody's word for it - including ours - spend five minutes proving it on your own line. Borrow a phone that is not yours, call your shop number, and find out.

  • Whose voicemail answers: Let the forwarded call ring out without picking up. Whose greeting plays - the shop's, or your personal cell's? This is the single most important thing to check, because if it is your cell's, then messages customers think they are leaving for the business are now sitting in a mailbox you check at nine at night.
  • What shows on your screen: When the forwarded call arrives, does your phone show the customer's number or your own shop number? If it shows the shop number, you cannot call anybody back from your missed-call list, and you will need the voicemail or a callback to get the number at all.
  • What happens on the second call: Have somebody call your shop number while you are already on a forwarded call. Does the second caller get call waiting, a busy signal, or voicemail? For a one-truck shop on a busy morning this is not a rare edge case, it is Tuesday.
  • Whether it survives a bad signal: A forward to a cell is only as good as that cell's coverage. If you work in basements, crawl spaces or metal buildings, the call still gets delivered - into a phone with no bars.

What forwarding does not fix

Set it up. It is free and it is better than nothing. Then be honest about what is left over, because this is where most shops stop and then wonder why the phone problem never went away.

A forwarded call still needs a person with a free hand. Moving the ring from the office to your pocket does not change what you are doing when it rings, and if you are elbow-deep in a panel or on a ladder, the outcome is identical - except now the missed call also feels like your fault. Forwarding solves a location problem. Most shops have an availability problem.

The call also ends somewhere you did not choose. When nobody answers a forwarded call it lands in whatever mailbox is at the end of the chain, and if that is a personal cell, your business messages are now mixed in with your dentist and your kid's school. And none of this touches the caller's side of it: somebody who called, heard it ring eight times and gave up is gone, and they are typically dialing the next shop on the list before your voicemail has even finished playing.

Forwarding, an answering service, and a text back

These three get talked about as alternatives, which is confusing, because only two of them are actually in the same business. Here is the honest version of what each one changes.

  • Call forwarding moves the ring: Free, instant, no third party. Changes where the call arrives and nothing else. Still requires you to be free.
  • An answering service adds a person: You forward your unanswered calls to a call center and an operator picks up using your script. Somebody is now available who was not before - which is the real difference - and you pay for it, usually by the minute or by the call. Our comparison of an answering service and voicemail goes through what that trade actually looks like.
  • A missed-call text back changes the channel: Instead of trying to get the call answered, it answers in writing. The caller gets a text back from the number they just dialed, and the conversation picks up from there - which works precisely because the customer does not need you to be free at that second, and neither do you.

When forwarding is the right call

It genuinely is the right answer sometimes, and it would be dishonest to write a page like this and pretend otherwise.

If you have an office line and somebody competent at the other end of the forward, forwarding is the whole fix. If your problem is purely nights and weekends and you are happy to take those calls personally, forward after hours and you are done. If the shop phone is a landline that rings in a building you left at two o'clock, forwarding is free money and you should stop reading and go set it up.

Where it stops being enough is the owner-operator case - the shop where the person who would answer the forwarded call is the same person doing the work. That is not a routing problem and no routing feature fixes it.

Forwarding also assumes you already have the two numbers you are routing between. If you are still at the stage of wanting a separate business line in the first place, our guide to getting a business phone number sets out the four options and what each one costs.

How Handlebar handles the same calls

Handlebar does not sit on your line or intercept your calls. Your phone, your number and your voicemail stay exactly as they are, and you can keep your forwarding set up however you like - the two do not fight.

What it adds is what happens after a call goes unanswered. Within about 60 seconds, the caller gets a text back from your shop's own number - not a canned one-liner, a real conversation that answers their questions, works out what they need, and books the job on the calendar you already use. It sends the confirmation when the job is set, the reminder before it, and the review request after it. The customer never had to wait for you to be free, which is the one thing forwarding cannot give you.

Common questions

Does call forwarding cost money?

The feature itself is usually free - Verizon's call forwarding page says there is "no monthly fee for Call Forwarding on most plans." The forwarded calls can cost, though. Verizon states that "If you don't have unlimited minutes, you'll be billed for all forwarded calls according to your plan. You'll be billed just like you would if you answered the call from your mobile phone." Carriers and landline providers differ, so ask yours two things: is there a monthly charge for the feature, and does a forwarded call use anything on the plan.

How do I forward my business calls to my cell phone?

You get the code from whoever bills you for the shop line, then dial it from that line with your cell number after it. As published examples, AT&T's small-business support lists "Press *72, enter a forwarding number, and then press #" to forward all calls and "*73#" to stop, and Verizon lists *72 plus the 10-digit number to start and *73 to stop. Have the destination phone in your hand when you do it - AT&T notes that activation "will automatically place a call to the number to which calls will be forwarded," and that call has to be answered for the forward to take.

What is the difference between forwarding all calls and forwarding only the ones I miss?

Forwarding all calls means the shop phone never rings at all - everything goes straight out to the other number. Forwarding only unanswered calls lets the shop phone ring first and sends the call onward only if nobody picks up in a few rings. AT&T publishes the second one as No Answer Call Forwarding (*92 to set, *93# to cancel), and Verizon describes *71 as forwarding "only the calls you don't answer." For a shop where somebody is sometimes at the desk, the second one is almost always the setting you want, and it is the one most shops have never turned on.

Is call forwarding the same as an answering service?

No, and the difference is who ends up on the call. Forwarding is a carrier feature that changes which phone rings - there is no third party and nobody new becomes available. An answering service is a staffed call center that you forward your unanswered calls to, so a person who was not there before now picks up, using a script you gave them, and you pay for that. Forwarding is often how the calls reach an answering service, which is why the two get confused, but on its own it adds nobody.

Can I forward a business landline to a cell phone?

Usually yes - landline and cable phone providers offer forwarding the same way mobile carriers do, you just get the code from that provider. Two things to check once it is working: whether an unanswered forwarded call lands in your cell's voicemail rather than the shop's, and what greeting that mailbox plays, because it is now a business greeting whether you wrote it as one or not. Verizon also notes the destination has to be an active, voice-capable, 10-digit US number, and that calls cannot be forwarded internationally.
