Registration conditions
- Who may register?
- According to Google Registry, open and without access restrictions.
- Length
- At most 63 characters per label (for IDNs the ACE form counts). This follows the DNS standard RFC 1035, which the ICANN registry agreement requires. The registry does not state its own minimum length.
- Characters
- a–z, 0–9 and hyphen. No hyphen at the beginning or end, and in positions 3 and 4 only for IDNs (ACE form starting with xn--).
- Registrant data
- Name, street, city, state/province and postal code where applicable, country, phone and e-mail of the registrant; an organisation is optional. Personal data is redacted in public lookups where data protection law requires it.
- HTTPS required
- .app is a secure extension: browsers load websites only over HTTPS, so a TLS certificate is required. Registrars must point this out before purchase.
- Two-character names
- Holders of two-letter names must not falsely imply a connection to a government or country-code registry.
- Term
- 1 to 10 years per registration or renewal (ICANN Registry Agreement).
- Transfer
- With an auth code (auth info) under the ICANN Transfer Policy. A lock period applies after a new registration or transfer.
- After expiry
- Restore possible during the Redemption Grace Period (ICANN rules).
- Disputes
- ICANN Uniform Domain-Name Dispute-Resolution Policy (UDRP).
The registry's current rules are binding: www.registry.google.
