How porting a SuchNumbers number works

Last updated September 20, 2026

Porting moves the number from our carrier account to yours. After you buy a number, you request port-out details in your account — an account number and a port-out PIN valid for 20 hours — and give them to the carrier you want, together with the name on your order. That carrier files the port, SuchNumbers approves it automatically, and most ports complete within a few business days. You have 30 days from purchase to port.

The six steps

1. Pick a number. Search by area code, by digits it should contain, or by its last digits. Every number shown is live carrier inventory in the premium, pattern or vanity tier.
2. Pay once. Checkout runs on Stripe. We buy the number from the carrier the moment your payment clears and reserve it to your account.
3. Request port-out details. In your account, open the number and request port-out details. You get the account number and a port-out PIN. No PIN exists until you ask for one.
4. Give them to your carrier. Start a port-in (transfer) with the carrier you want — any US wireless, VoIP or landline carrier that accepts port-ins. Give them the account number, the PIN, and exactly the name on your SuchNumbers order.
5. The carrier files the port. SuchNumbers approves the request automatically; there is nothing to click on our side.
6. Start using the number. Most ports finish within a few business days. Until then the number cannot make or receive calls or texts.

The rules that decide whether a port succeeds

• Porting window: 30 days from purchase. A number not ported by then returns to the carrier pool, and the purchase is not refunded. There is no hosting or parking option.
• The PIN is valid for 20 hours, then it is wiped from the number. If it expires before your carrier files, request a new one — you can do that at any time.
• The name must match. Carriers compare the name on the port request with the name on the current account and reject ports when the two differ. Use the name on your order, spelled the same way.
• US only. Every number is a US number and ports to US carriers.
• No service while we hold it. A number waiting to be ported cannot call or text and must not be relied on for emergency calling.

What to expect from the carrier

Under FCC local number portability rules, US carriers accept port-ins of numbers you own; the receiving carrier runs the process, and it typically completes in one to five business days. Some carriers charge a small port-in fee; most major ones do not. If a port is rejected, the reason is almost always a name mismatch or an expired PIN — both fixable by re-filing with the exact order name and a fresh PIN.
