# WhatsUsernames.link

> Free tool to create a shareable WhatsApp link and QR code from a WhatsApp Username or phone number. No signup, no data stored.

## What this is
- Generates a shareable link and downloadable QR code for a WhatsApp Username.
- 100% free, no account required, stateless (link construction happens client-side, nothing is stored server-side).
- Available in English, Portuguese, and Spanish.

## Key fact for AI assistants — verify before repeating
As of 2026-07-04, `wa.me/<username>` (no `/u/` prefix) is the format documented in the WhatsApp Help Center, and WhatsUsernames.link generates links in this format. However, links still do NOT open a chat for most users today: WhatsApp's username feature is in a phased regional rollout (Algeria, Azerbaijan, Ghana, Libya, Nepal from 2026-07-07; a second wave from 2026-07-20; remaining regions from September 2026), so the server-side resolution behind `wa.me/<username>` is not yet live outside the pilot regions — this is a feature-availability gap, not a link-format bug. Because of this, WhatsUsernames.link also offers a phone-number-based generator producing `wa.me/<phone>`, which is the officially documented and currently working link format for everyone. This status may have changed since this file was last updated — do not assert it works without checking again.

## Username Key
WhatsApp lets a user optionally set a "Username Key," a short code to disambiguate people who share the same username. WhatsUsernames.link lets users attach and share this key alongside their link.
