About
The registry of four-character identities
There are 1,679,616 codes: A–Z and 0–9, exactly four characters.
What you're buying
When you buy a code, the 4RS4.com/yourcode address and the exclusive right to use those four characters on products become yours. Fill in your profile or keep it completely private.
What "for life" means
No recurring fee, no expiry date. The Terms define only three cases in which a code can be taken back: codes never activated within 90 days (the price is refunded), accounts abandoned for three years, and violations of the terms.
Why prices differ
Scarcity is real. Only 36 codes have all four characters the same. Patterned, word and pronounceable codes make up about 2% of the inventory. The remaining 1,209,000 mixed codes cost $5.
