FAQ

Frequently asked questions

Common questions about this page, the underlying products, and the verification workflows we run for B2B teams.

How many checker products does BulkChecker offer and across how many platforms?
BulkChecker offers verification across 28+ platforms, grouped into 8 product clusters: phone validation, carrier lookup, WhatsApp, Telegram, messaging apps (iMessage, Viber, RCS, Signal, LINE, Zalo, Band), social platforms (Facebook, Instagram, X/Twitter, Snapchat, Threads, Messenger), account verification (Apple ID, Microsoft, Amazon, Netflix, Spotify, GoTo, Indiatimes), and crypto exchanges (Binance, KuCoin, HTX, CoinW).
Do all products share the same API and CSV upload?
Yes. Every product on this page is accessible through the same REST API and the same CSV bulk upload — one account, one credit pool, all platforms. No per-platform integration required.
How is pricing structured across these products?
Pricing is pay-as-you-go, denominated per 10,000 lookups, and varies by platform difficulty — phone validation and carrier lookup start at $4/10K, while complex platform checks (Binance, Microsoft) run higher. See the pricing page for the full matrix.
Can I bundle products or build a custom workflow across multiple checkers?
Yes. Most B2B teams chain 3–5 checkers — for example: phone validator → carrier lookup → WhatsApp checker → fraud score. Inside the dashboard, upload one CSV and run multiple checks sequentially, or call the API in a single batch job.
Do you offer enterprise SLAs and dedicated support?
Yes. For high-volume customers (>10M lookups/month), we offer dedicated infrastructure, SLAs, custom rate limits, and a named CSM. Contact sales for enterprise pricing.
