What is the difference between the subscriber, account holder and user of a number?¶

A provider record may name one person against a telephone number.

Evidential caution: that the named person must be the user of the number.

What this means¶

The subscriber is usually the person or organisation recorded by the provider as holding the service.

The user is the person who actually controlled the number, SIM, device or linked application at the relevant time.

These roles may all belong to one person, but they may also be different.

A parent may hold the account while a child uses the number. A company may subscribe to the service while an employee uses the handset. A fraudster may take over the number through a SIM swap. A shared phone may pass between several users.

Then seek evidence of actual use: device possession, SIM association, linked messaging accounts, login activity, location, communications patterns, witness evidence and admissions.

Report each relationship separately. The provider may identify the subscriber while other evidence identifies the user.

What to check or do next¶

• Preserve the provider’s exact terminology. Do not treat “subscriber”, “customer”, “account owner” and “user” as interchangeable unless the records support that meaning.
• Establish the relevant date. A number may have been reassigned or transferred between account holders.

Evidential limits¶

The account holder may be the person responsible for billing or managing the wider account. On a family or business account, that person may not use every number attached to it.
