Volume
Rates from 1M+ lookups a month
Volume tiers are based on total monthly usage across every product. Your tier loads onto the account and applies to each job automatically — no codes, no monthly renegotiation.
Enterprise & volume
Volume pricing for teams that run millions of lookups
The published rate card covers most teams. If you push more than 1M lookups a month, message us and we will build one around your volume, your products, and your send windows.

What to include in your message
Three lines is enough for a quote.
- Monthly volume — rough is fine. “3–5M lookups a month” works.
- Products — which checks you run, or the job mix if it varies.
- API or CSV — how you run jobs, and any deadlines your send windows impose.
Quotes go out the same business day, with a recommended rate card attached.
What you get
Four things the rate card alone does not include
Everything on the public pricing page stays available to you. Enterprise terms sit on top of it, not instead of it.
API
Custom rate limits
Default concurrency caps exist to protect shared capacity. At volume we raise them to match your send windows, so a full list clears inside the slot you planned for it.
Support
Written SLA & 24/7 support
Response targets in writing, with an escalation path that reaches an engineer rather than a queue. Overnight jobs get the same treatment as office-hours ones.
Account
A named account manager
One person who knows your products, your list profile, and your routing setup. You message the same human every time instead of re-explaining your setup to a ticket queue.
Why ZelNum
What your volume is actually buying
Every answer comes from the network
Each result is a live query at the moment you ask — nothing is served from a cache. At a million lookups a month, the gap between a live answer and a six-month-old database row is the gap between a clean list and a burned send.
39 checks, one balance
Phone validation, carrier lookup, WhatsApp, Telegram, and the rest of the catalog run on one prepaid balance, so mixing products never means mixing invoices or minimums.
No subscription to negotiate
Volume tiers change your rates, not your purchasing model. You keep topping up credits as you go, which keeps procurement simple and gives finance one clean line item.
FAQ
Enterprise volume questions
How do volume discounts work?
Rates are tiered by monthly lookup volume across all products. Once your usage passes 1M lookups a month, we build a custom rate card and load it on your account, so every job is billed at your tier automatically.
Do you sign DPAs and custom agreements?
Yes. We sign DPAs, order forms, and written SLAs. Data handling terms are published on the Data & Compliance page, and the signed agreement adds your response-time targets and escalation path on top.
What counts as one lookup?
Each row submitted to a bulk job is one lookup, and each realtime query is one lookup. Failed lookups are recredited to your balance automatically, so you never pay for an answer you did not get.
How fast do we get a quote?
Same business day on WhatsApp or Telegram. Include your monthly volume, the products you need, and whether you work over the API or CSV uploads, and the quote comes back with a recommended rate card.
