# CNAM Preset Troubleshooting

#### Before you start

Check if your CNAM association is valid. Review our [Guidelines](/flowroute-support/docs/outbound-caller-id-name-cnam-storage-configuration).

CNAM assignments are only applicable to customers calling within the United States.

Flowroute cannot provide CNAM to carriers outside of the United States due to service limitations. However, Canada is able to receive CNAM data only through the **P-Asserted-Identity** tag. Be aware that this information must be assigned manually on your phone system/PBX. Canadian carriers may ignore this value and be unable to use this CNAM assignment.

**NOTE:** *CNAM must be approved by Flowroute Team before any DIDs can be assigned to it.*

### Errors you may encounter while setting up CNAM

#### No eligible DIDs

You see this error message when you are adjusting a new CNAM:

"None of the DIDs that you selected are eligible for CNAM storage service. Please change your selection and try again. Note that DIDs on a port order are not eligible until the order completes."

**Possible Solutions:**

1. Review DIDs you selected:
  1. Only **US local numbers** can be associated with CNAM Preset.
  2. Note that DIDs on incomplete Port Orders are not eligible for CNAM assignment - wait until Port Order is complete.
2. Try setting up CNAM storage via [Flowroute API](https://developer.flowroute.com/api/numbers/v2.0/assign-a-cnam-record-to-phone-number/)
3. Contact Support at [support@flowroute.com](mailto:support@flowroute.com)
  1. Make sure to include:
    1. The DID(s) you are having issues with
    2. Description of the issue you're encountering
    3. The Email and Tech Prefix from your [Flowroute account Dashboard](https://manage.flowroute.com/)
    4. The CNAM Preset you are attempting to use
