3CX Licenses

Renew or upgrade an existing license

Paste your 3CX license key below to see live renewal and upgrade prices. All prices are ex-VAT in GBP.

Keys are 16 characters in 4 groups, e.g. ABCD-EFGH-IJKL-MNOP.

What happens next

  • We look up your license against the 3CX partner API to confirm the edition, call capacity, expiry and hosting status.
  • Choose a renewal term (1, 2 or 3 years) or switch to a higher edition / more simultaneous calls.
  • We'll show the price (ex-VAT) before you commit - nothing is charged at this step.
