Random Phone Generator

What it does

The Random Phone Generator produces synthetic phone numbers in US, UK, or international formats — output as human-formatted ((555) 123-4567), E.164 (+15551234567), or bare digits. Generate up to 10,000 per run, seeded so fixture files stay stable.

Common use cases

• Database fixtures — phone columns for user and contact tables (presets for default, US bulk, and international sets).
• Form and validation testing — country-appropriate formats for the accept path of phone validation.
• Normalization testing — the same numbers in formatted vs E.164 vs digits exercise parsing and canonicalization code.
• UI prototypes — realistic numbers in contact lists, call logs, and SMS mockups.

Settings

• Country — US, UK, or international; formats follow each region’s conventions.
• Format — formatted with separators, E.164 (+ and country code, the storage standard), or digits only.
• How many — 1 to 10,000 numbers, exportable as text, CSV, or JSON.
• Seed — identical seed + settings = identical numbers.

Privacy note

Numbers are generated locally in your browser and never uploaded. They are fictional — not sampled from real directories — but a generated number may coincide with a real line, so never call, text, or send verification codes to generated numbers. Display and parsing only.

FAQ

Which format should I store? E.164 — it’s unambiguous, sortable, and what telephony APIs expect. Format for humans at display time. Generating matched sets in both formats makes conversion tests trivial.

Will these pass validation? Format validation, yes. Line-existence checks (carrier lookups) will mostly fail — useful for testing that layer separately.
