# SIP CredentialList Resource

SIP **CredentialList** resources contain the credentials of the users who are allowed to reach your SIP Domain. We only allow traffic from users who have their credentials in the credential list.

For information about the individual **Credential** resources in the list, such as to create, list, read, update, or delete individual credentials, see the [Credential Resource](/docs/voice/sip/api/sip-credential-resource).

After you create a CredentialList resource, you will need to [map it to your SIP domain](/docs/voice/api/sip-interconnect) for it to take effect. You can map a CredentialList to more than one SIP domain.

Your Account can have up to 100 **CredentialList** resources.

Each **CredentialList** resource can contain up to 1,000 unique users.
