# 60426: Verification ID invalid or not provided

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs when your Verify request sends a missing or malformed Verification SID. Verify uses Verification SIDs that start with `VE`, and the `verificationSid` value must match the expected SID format when you check a verification by SID.

### Possible causes

* The request does not include `verificationSid` when your integration is trying to identify the verification by SID instead of by `to`.
* The Verification SID is incorrectly formatted and does not match `^VE[0-9a-fA-F]{32}$`.
* The value sent in `verificationSid` is not the `verification.sid` returned when you created the verification.
* The request sends a different SID type, such as a Service SID that starts with `VA`, instead of a Verification SID that starts with `VE`.

### Possible solutions

* Pass the `verification.sid` returned by the create Verification response if you want to check the verification by SID.
* Validate that the `verificationSid` value starts with `VE`, is 34 characters long, and matches `^VE[0-9a-fA-F]{32}$` before you send the request.
* If you are not checking the verification by SID, send the `to` parameter instead. Verify accepts either `to` or `verificationSid` for a Verification Check request.
* Make sure you send the Verification SID in the correct request field and do not substitute another resource SID, such as the Verify Service SID.
