A2P 10DLC Campaign Vetting Delays: We are experiencing delays while vetting 10DLC campaigns. Our third party is reviewing campaigns manually, and due to the high volume of requests, a queue has built up. Campaign reviews are expected to take longer. Twilio is working with the provider to help expedite this process. New details will be shared in our incident report as soon they become available.

How Does Twilio Validate my Tax ID?

Are you having a hard time entering a valid VAT, GST or other Tax identification number in Twilio Console? This guide explains the accepted Tax ID formatting.

Notice: If Twilio's validation rules won't accept a Tax ID you believe to be valid, please contact our Support team with documentation to prove your tax registration, or evidence to show you are a business.

VAT in Europe

If you are in the European Union, United Kingdom, Norway, Switzerland, or Liechtenstein, you are requested to enter your VAT registration number into Twilio Console. Please input the VAT registration number based on the standard formatting for your country. If you are unsure of your VAT format or validity, please validate the number at a site like vatlayer.com.

VAT number field tips:

  • VAT numbers may or may not have spaces - either way is accepted.
  • The VAT number can be preceded by the country code, but this is not required. If the country code is not included, Twilio will use the country code from your service address.
  • Some countries have special formatting rules: ex. Switzerland VAT numbers must be formatted 123.456.789 and end with MWST, TVA, or IVA

GST in Australia

If you are in Australia, you are requested to enter your GST registration number into Twilio Console. Please note that not every customer who has an ABN is registered for GST; you are expected to add your GST number only if you are registered for GST. Your GST number will be verified against the standard ABN format.

GST in Singapore

If you are in Singapore, you are requested to enter your GST registration number into Twilio Console. Please note that depending on the company type, customers may need to use a standard GST registration number, a National Registration Identity Card (NRIC) Number, or a Unique Entity Number (UEN).

You can validate your GST, NRIC, or UEN number at the Singapore GST Registered Business Search (mytax.IRAS.gov.sg). Here are examples of how the different numbers may be formatted:

Tax identification type Description Example
GST Registration Number Business under GST registration, Sole proprietorships MX1234567X

GST in Canada

If you are in Canada, you are requested to enter your GST/HST/PST/QST registration number into the Twilio Console. Please note that depending where you are located you may have to provide your GST/HST or both your GST and your provincial number (PST or QST).

You can validate your tax number(s) as follows:

Your tax numbers should be entered in the following format: 

  • GST/HST number: A GST/HST account number is a unique 9-digit number. It can be followed by 6 additional characters used to identify divisions of a given corporation, being the most commonly used RT0001. For validation purposes, enter only the first nine digits. Example 123456789  or 123456789 RT 0001
  • Quebec QST number: The QST registration number has 16 characters:  10-digit number followed by the letters TQ and four more digits. The last 4 digits of the registration number are seldom provided by suppliers, however you should note that the extension TQ0001 is the most commonly used. It can start with "NR" followed by eight digits for non resident taxpayers. Example 1234567899 TQ 0001
  • Saskatchewan PST number: It is a unique 7-digit number.  Example 1234567
  • British Columbia PST number: A PST-BC account number is a unique 8-digit number without letters, issued by British Columbia Finance. Example 9999-9999
  • Manitoba PST number: A PST-MB account number is a unique 7-digit number or the 9 digit GST ID attached to six characters suffix.  Example 999999-9 or 850082157MT0002 or 792702136MC0001
