How to forward calls
Two ways to do it — your phone's settings or a dial code — and three codes that cover every carrier. Here's the fastest path for your phone.
The fastest way: three universal star codes
Most US and Canadian carriers use the same three North-American star codes, dialed straight from the phone whose number you want to forward — no app, no portal:
*72— forward every call immediately. Your phone never rings; everything goes to the destination number. Dial*72followed by the destination, e.g.*7218005551234, then press call and wait for the confirmation tone.*71— forward only when busy or unanswered. You still answer when you're free; calls you miss (busy, or no answer in ~4 rings) roll to the destination. This is the one most businesses want.*73— cancel forwarding. Dial it from the same line you set it on.
These work on Verizon, Spectrum, Xfinity, and most landline and VoIP lines. AT&T and T-Mobile use a slightly different format (**21* to forward all, **61* for conditional, ##21# to cancel). The generator below gives you the exact code for your carrier.
From your phone's settings (no codes)
If you'd rather not dial a code, every smartphone has a forwarding toggle built in:
- iPhone: Settings → Phone → Call Forwarding → toggle on → enter the destination number. (Works on GSM carriers like AT&T and T-Mobile; Verizon and other CDMA lines use the star codes above instead.)
- Android / Samsung: open the Phone app → ⋮ menu → Settings → Calls → Call forwarding → choose *Always forward* or a conditional option → enter the number.
The settings toggle and the star codes do the same thing — use whichever is faster on your phone. Full walkthroughs: forward calls on iPhone, on Android, and on Samsung.
Forward every call vs. only the ones you miss
The key decision is unconditional vs conditional forwarding.
Unconditional (*72) sends every call away — use it when you'll be unreachable for a stretch: vacation, a conference, or handing off to after-hours coverage.
Conditional (*71) only forwards when your line is busy or goes unanswered — you keep answering the calls you can take, and only the overflow forwards. This is the setup most small businesses want, because it pairs your own phone with a safety net: you handle what you can, and nothing else drops to voicemail. More detail: conditional vs unconditional forwarding.
How to turn call forwarding off
To cancel, dial *73 from the line that has forwarding active (AT&T/T-Mobile: ##21#), and wait for the confirmation tone. If you set up both *72 and *71, run the cancel code for each.
If calls still forward after cancelling, test by calling the line from another phone — and check whether forwarding is also toggled on in your phone's settings menu, since the two methods are independent. Full steps: how to cancel call forwarding.
Where should you forward your calls?
Forwarding only helps if something useful answers on the other end. The common destinations:
- Another phone — your cell, a partner, or a teammate. Fine until that line is also busy.
- Voicemail — better than a missed ring, but most callers hang up without leaving a message and many never call back.
- An answering service — a person or an AI that actually picks up, answers questions, and books the appointment.
That last option is what closes the loop. Forward your line (conditional *71 is ideal) to RingOwl, and an AI receptionist answers every forwarded call in under a second, books appointments straight into your calendar, and texts you a summary — 24/7, for a flat monthly rate.

FAQ
- What is the code to forward calls?
- On most US and Canadian carriers (Verizon, Spectrum, Xfinity, landline/VoIP), dial *72 followed by the destination number to forward every call, *71 to forward only busy/unanswered calls, and *73 to cancel. AT&T and T-Mobile use **21* to forward all, **61* for conditional, and ##21# to cancel. Use the generator above to get the exact code for your carrier.
- How do I forward calls without dialing a code?
- Use your phone's settings. On iPhone: Settings → Phone → Call Forwarding. On Android/Samsung: Phone app → menu → Settings → Calls → Call forwarding. Toggle it on and enter the destination number. The settings toggle does exactly the same thing as the star codes.
- What's the difference between *72 and *71?
- *72 forwards every call immediately — your phone never rings. *71 only forwards when your line is busy or doesn't answer in about four rings, so you can still pick up directly when you're free. Most small businesses want *71.
- Will I be charged for forwarded calls?
- Forwarded calls are billed to your line the same as a normal outbound call from that line to the destination. On unlimited plans this is usually included; on metered plans it counts against your minutes. Check your specific carrier plan if you're unsure.
- Why isn't my call forwarding working?
- Three usual causes: (1) you dialed from a different line than the one you're forwarding — codes only affect the line they're dialed from; (2) forwarding is disabled at the account level — check your carrier's calling features; or (3) the destination number had spaces, dashes, or a country code — strip it to a plain 10-digit US number.
