I have submitted my VAT number, but the system is not accepting it. I have a valid VAT certificate that proves what my VAT number is. It is in the GB999 9999 99 format. Still thje system is not accepting it.
Please check the format shown here. You can add the VAT number by going to Settings > Tax Information. If the tax ID that you submit isn't in the format provided by VIES, Upwork won't be able to validate it. You can check if your VAT number will be validated on the VIES website here. After you submit your VAT number to Upwork,Upwork will validate the number and email you to confirm whether it was validated or declined. We are currently experiencing longer processing times than expected but it typically takes up to 3 business days for Upwork to validate your VAT number.
