Why port requests get rejected
Almost every rejection is a mismatch between your paperwork and the losing carrier’s customer service record.
Is a rejection a refusal?
A rejected port is rarely a refusal. It is an automated comparison failing: the losing carrier checks your request against its customer service record, and anything that does not match exactly comes back as a rejection. Most are fixed in a day once you know which field is wrong.
What each rejection reason means
| Reason given | What it means | How to fix it |
|---|---|---|
| Business name mismatch | The name on your request is not the name on the carrier record — often a trading name instead of the legal entity, or a since-changed name. | Copy the account name exactly as printed on a recent bill, including punctuation and any abbreviation. |
| Service address mismatch | The address on file differs from the one submitted. Billing address and service address are often different. | Use the service address from the bill, character for character. Do not normalize "Ste" to "Suite". |
| Wrong billing telephone number | The BTN is the main number the account is filed under, and it is not always a number you use day to day. | Take the BTN from the bill header, not from the list of lines. Ask the losing carrier if the bill is ambiguous. |
| Wrong account number | The number submitted is not the account number, or includes a location or invoice suffix that should not be there. | Read it from the bill or the account portal. Some carriers also require a separate porting PIN. |
| Pending order on the account | A move, an upgrade or a feature change is already open on the account, and it blocks the port. | Ask the losing carrier to complete or cancel the pending order, then resubmit. |
| Account freeze or port-out lock | A protection setting on the account blocks transfers out, sometimes enabled by default. | Only the account holder can lift it. Call the losing carrier and ask for the port-out lock to be removed. |
| Number is part of a bundle | The number is tied to a package and cannot be released on its own. | Ask what has to be unbundled first, and confirm the number is contractually yours before proceeding. |
| Unpaid balance | The losing carrier cites money owed on the account. In practice this stops ports, but FCC guidance is that a provider should not refuse to port a number just because you owe it a balance or an early termination fee — it can bill you, and pursue you, but the number is meant to move. | Settling the balance is the fastest route. If you believe the charge is wrong, say so in writing, ask your new provider to press the point, and keep the correspondence. |
| Invalid or expired authorization | The letter of authorization is unsigned, signed by someone not authorized on the account, or too old. | Have an authorized signer re-sign a current letter. Check who is actually listed on the account first. |
How to clear a rejection quickly
Get the exact reason in writing
Ask your new provider for the rejection code and text as the losing carrier sent it, not a paraphrase.
Pull a bill from the last 30 days
An older bill may show details that have since changed, which is how a second attempt fails the same way.
Ask the losing carrier for the record
You are entitled to know what name, address and BTN they hold. That one call resolves most repeat rejections.
Correct one field and resubmit
Changing several at once makes it harder to tell what actually fixed it if the next attempt fails too.
Keep the old service live throughout
A rejection does not pause your old contract, and canceling mid-process loses the numbers.
When it is not a paperwork problem
A small number of rejections are structural rather than clerical. A number outside the rate center your new provider serves, a toll-free number submitted on the geographic process instead of as a registry change, or a number that was never yours will keep failing however carefully you fill in the form. If two clean attempts are rejected for the same reason, stop resubmitting and ask what the underlying constraint is.
Rejection codes, wording and internal practice vary by carrier, and this is general guidance rather than a statement of your rights in a particular dispute. If you think a number is being held rather than validated, your new provider is the first place to raise it, and a complaint to the FCC or your state commission is the next — see where to escalate.
For what you should have gathered before the first submission, see keeping your phone numbers.
