Core Rules For A Valid Authorization Letter

Missing just one required detail will result in your letter being rejected 90% of the time. Every valid letter must include all items on this checklist:

  • Your full legal name, contact details and official ID number
  • The authorized person’s full legal name and matching ID number
  • Exact specific permissions, no vague wording
  • Clear start and end dates for the authorization
  • Your handwritten signature and the date written

The level of detail required changes for different situations. Refer to this quick reference:

Use Case Detail Level Required
Collect post / parcels Low
Bank transactions High
Legal / medical tasks Very High

Frequently Asked Questions about Sample Letter to Authorize Someone

Does an authorization letter need to be notarized?

Most routine uses like parcel collection do not require notarization. For bank, legal or medical matters, always confirm the policy of the receiving organisation first.

Can I send an authorization letter via email?

Most modern organisations accept scanned signed letters via email. Always confirm this first, and keep the original hard copy signed letter for your own records.

How long can an authorization letter be valid for?

You can set any valid date range. It is best practice to use the shortest possible period required for the task. Avoid open ended authorization unless absolutely necessary.

What ID should the authorized person carry?

Always specify one government issued photo ID in the letter. This can be a driver’s license, passport or state ID card. Digital copies are usually not accepted.

Can I cancel an authorization letter once sent?

Yes, you can cancel an authorization at any time. Send a formal written cancellation notice to the receiving organisation and notify the authorized person.

Can I write an authorization letter by hand?

Handwritten letters are accepted as long as they are legible and include all required details. Typed letters are preferred by most official organisations.

Do both people need to sign the letter?

Only the person granting permission needs to sign the letter. The authorized person does not need to sign, they only need to show their ID when attending.

Is a text message or verbal permission enough?

No official organisation will accept verbal or text message permission. All formal requests require a signed written authorization letter for verification.
