🚧 Alpha — upcoming in v1.0.16 (target: October 8, 2026). This feature is not yet live in production. The flow and payloads below are final per stage testing but may change until go-live. This page is published early so the link stays stable; it will be promoted to live once v1.0.16 ships.Cancelling a number deactivates it with the carrier immediately. To stop numbers being cancelled by mistake, cancellation always takes two API calls:
- Request the cancellation — you get back an AuthCode.
- Submit the cancellation with that AuthCode — only then are the numbers cancelled.
⚠️ You cannot cancel a number without an AuthCode.If the code expires or is used up, send a new
- Every cancellation needs the AuthCode returned by
cancel-order-request.- The AuthCode is valid for 5 minutes only.
- Each AuthCode works once, for one order.
cancel-order-requestto get a new one.
How it works
Before you start
- Authentication: API tokens are bound to one endpoint, so you need a token for each of the two endpoints:
/v1.0/numbers/cancel-order-requestand/v1.0/numbers/cancel-order-submit. - Cancel is no longer accepted on
/numbers/status. Sending"StatusChange": "cancel"there returns HTTP400:Cancel has moved to POST /numbers/cancel-order-request. - No future-dated cancellations. There is no effective date — a submitted cancellation happens right away.
Step 1 — Request the cancellation
Number is not active '...' (see Errors). The only time an already-cancelled number appears in FailedChange instead is when it is cancelled by something else between your request and your submit — see Step 2.
Response
OrderId and AuthCode — you need both for step 2.
- Check
NumbersChange. These are exactly the numbers that will be cancelled. If anything is wrong, simply don’t submit — the order expires on its own. - Read the
ConsentStatement. Submitting in step 2 counts as accepting it.
The AuthCode
The AuthCode is what turns a cancel request into an actual cancellation.💡 Best practice: submit straight after you’ve reviewed the request, well inside the 5 minutes. If you need longer (for example to get approval), send a new request when you’re ready.
Step 2 — Submit the cancellation
Response
If you subscribe to Order_Update webhooks, you also receive one webhook with the order’s final status.
After cancellation — the 30-day window
List numbers still in the window with the inventory filter:
ℹ️ Reactivation of aCancelled - Pending Deletenumber (within 30 days, $5 recovery fee) is delivered byPOST /v1.0/numbers/reactivate. Self-service reactivation ships in or shortly after v1.0.16 — see the Reactivate endpoint page for its status.
Errors
Business errors return HTTP 400 with a message, and nothing is cancelled.⚠️ One non-400 case to watch. The two calls use separately scoped tokens. Sending thecancel-order-requesttoken tocancel-order-submit(or vice versa) returns401 Unauthorized— not a 400. If submit returns 401 while your AuthCode is counting down, check you’re using the submit token.
cancel-order-request
cancel-order-submit
An already-cancelled number is normally rejected earlier, at
cancel-order-request, with Number is not active '...' (it is no longer Active). It only reaches FailedChange here when a number is cancelled by something else between your request and your submit — in that case it comes back with a clear error rather than being cancelled again, for example: Number is already cancelled '+12015550101' (Cancelled - Pending Delete).
Quick checklist
- Get a token for
cancel-order-requestand one forcancel-order-submit. - Call
cancel-order-requestand keep theOrderIdandAuthCode. - Check
NumbersChangeand read theConsentStatement. - Call
cancel-order-submitwithin 5 minutes (beforeAuthCodeExpiresAt). - Check
OrderStatusandFailedChangein the response. - If the code expired, start again from step 1.
FAQ
Can I reuse an AuthCode? No. Each code works once, for the one order it was issued with. I lost the AuthCode — can Telegent resend it? No. Only a hashed form is stored. Send a newcancel-order-request, which also expires the old order.
Can I get a longer expiry? No — the expiry is fixed at 5 minutes. Request the cancellation only when you’re ready to submit it.
What if I change my mind after step 1? Do nothing. The order expires after 5 minutes and no numbers are affected.
What if I change my mind after step 2? The numbers are already deactivated. During the 30-day pending-delete window, reactivate each one with POST /v1.0/numbers/reactivate for a $5 recovery fee per number. After 30 days they can’t be recovered.
Can I schedule a cancellation for a future date? Not at the moment. Every cancellation happens when it’s submitted.
Want to deactivate a number but keep it? Park it instead of cancelling — parking keeps the number reserved for you without deactivating it. See your MSA fee schedule.
