Proof Holdings vs Bird (MessageBird)
Bird is a capable omnichannel engagement platform — SMS, WhatsApp, email, RCS, Instagram in one place — and if that's what you're buying, verification rides along. Bought as verification alone, it's a marketing suite with layered fees and a pass/fail at the end.
Buy Bird for engagement; buy Proof for proof. Purpose-built verification at the same price in every country, user-initiated verification with no code to lose in delivery, and a signed ES256 token at the end of every flow.
One API · One key
One key does what a stack of vendors does
Every provider on this page delivers codes to phones. Proof is a single API — the same reverse-OTP flow also covers email and domains, and every verification mints a signed, offline-verifiable ES256 token for each of these:
Same price · Any asset

The Hidden Cost: Country-Variable Pricing
Bird's (MessageBird) pricing has multiple layers: platform access fees, volume commitments, channel-specific charges, and carrier surcharges. The total cost per verification depends on your volume, which channels you use, and which country the user is in.
International SMS costs vary from $0.05 to $0.50+ per message depending on destination. Carrier surcharges are added on top. Premium routing costs extra. The final per-verification cost is unpredictable.
Proof Holdings charges from €0.0079 per proof — the same in any country, any asset type. No platform fees, no volume commitments, no carrier surcharges. The price is the price.
Omnichannel Platform vs Purpose-Built Verification
Bird is a full omnichannel customer engagement platform — SMS marketing, WhatsApp campaigns, email newsletters, RCS, Instagram DMs, Facebook Messenger. Verification is one feature among many.
Proof Holdings is purpose-built for verification and trust. Every feature — Reverse OTP, proof tokens, HITL approvals, MCP integration — is designed around proving asset control with cryptographic evidence.
If you need a customer engagement platform that also does verification, Bird makes sense. If you need verification that's reliable, affordable, and produces portable proof tokens, Proof Holdings is the better fit.
Security
Bird's SMS and voice verification channels are vulnerable to SIM-swap attacks and to SMS delivery failures.
Proof Holdings uses Reverse OTP — the user sends a message to the service, not the other way around. No code to deliver, intercept or phish, and on Telegram and WhatsApp a SIM swap alone is not enough. Every verification produces an ES256 JWT proof token verifiable offline.
When to use Bird (MessageBird)
- You need a full omnichannel customer engagement platform (SMS, WhatsApp, email, RCS, social)
- Verification is a secondary feature in your marketing/engagement stack
- You're already in the Bird ecosystem for customer communications
When to use Proof Holdings
- Verification is your primary need, not omnichannel marketing
- You need to verify more than phone numbers (email, domain today; wallet & social soon)
- You want predictable pricing without country surcharges
- You want cryptographic proof tokens and no codes lost in delivery
- You need HITL approvals for AI agents
