United Domains has catalog evidence for 772 extensions; 772 extensions also have a recorded standard price. The latest price observation in this profile is dated Nov 8, 2026.
A supported extension only needs evidence that the registrar offers it. A priced extension additionally needs a recorded standard-price observation. An extension without a displayed price is not assumed to be free, unavailable or unsupported.
Use the table to compare standard registration, renewal and transfer prices for a selected extension. Open the extension for the seller-specific detail and price history; check a full domain name separately for availability and premium classification.
