Validation Rules

Authorisation number formats

Getting your patient pre-authorised gives you peace of mind that their policy allows them to have the requested treatment. But remember, it’s not a guarantee of payment. Adding the pre-authorisation number (sometimes also known as claim number or patient assessment number) onto your invoice shows the insurer that someone has been in touch prior to treatment to let them know what’s going on. If you’re going to add it you need to make sure the format is correct to stop your invoices failing validation.

The pre-authorisation number is optional for the insurers, unless otherwise stated. The only insurer that doesn’t validate these is AXA Health, so we haven’t included the format requirements in this guide.

The validation format criteria are set out for each insurer and use the following key:

  • A = Letter
  • N = Number
  • X = Letter or Number

A couple of examples:

  • AANNNN = 2 letters followed by 4 numbers
  • NNNNNNXXA = 6 numbers, followed by 2 characters than can either be a number or a letter, followed by a letter

Where other letters and specific letters or symbols are used, this is clearly shown.

Alliance Health

There are two formats that’ll pass validation.

  • AAANNNNN = 3 letters, followed by 5 numbers
  • A-ANNNNN = a letter, followed by a hyphen (-), followed by a letter, followed by 5 numbers

Allianz Partners

There’s no set length – it can be a combination of letters, numbers and can also include a hyphen.

There are four formats that’ll pass validation.

  • NNNNNN/NN/NNNN/NNN = 6 numbers, followed by a forward slash (/), followed by 2 numbers, followed by a forward slash, followed by 4 numbers, followed by a forward slash, followed by 3 numbers
  • NNNNNN\NN\NNNN\NNN = 6 numbers, followed by a backslash (\), followed by 2 numbers, followed by a backslash, followed by 4 numbers, followed by a backslash, followed by 3 numbers
  • NNNNNN/NN = 6 numbers, followed by a forward slash (/), followed by 2 numbers
  • NNNNNN\NN = 6 numbers, followed by a backslash (\), followed by 2 numbers
