# Delete an incoming phone number

`DELETE /Accounts/{AccountSid}/IncomingPhoneNumbers/{Sid}`

Releases an Incoming Phone Number and removes it from the account. This is for numbers the account should no longer own; changing or deleting a handler does not release the number. Native phone-number resources use [Release phone number](/docs/apis/rest/phone-numbers/release-phone-number).

Note: Numbers cannot be released within a cooldown period after purchase.
