FAQ

Frequently asked questions about solutions

What makes phoneveriflo solutions different from standard phone validators?

phoneveriflo combines deterministic preflight analysis with cryptographic HMAC caching, double-entry ledger accounting in integer micros, and complete provider neutrality. You see exact invalid and duplicate counts before paying a single cent, ensuring zero price surprises.

Are invalid format numbers or duplicates charged?

Never. Our preflight engine identifies obvious syntax errors and exact duplicate entries within your batch and marks them as zero-cost ($0). You are only billed for unique, valid records requiring verification.

How does cryptographic HMAC caching work?

We derive one-way cryptographic keys using HMAC-SHA256 with a private pepper salt. Result payloads are encrypted with AES-256-GCM at rest, strictly isolated to your workspace tenant, and capped at a maximum 90-day TTL. Cached lookups are billed at up to 75% discount compared to fresh lookups.

Can I integrate phoneveriflo into existing CRM and warehouse pipelines?

Yes. phoneveriflo provides high-performance REST APIs, HMAC-SHA256 signed webhooks, and flexible CSV/JSON export capabilities compatible with Salesforce, HubSpot, Snowflake, BigQuery, and custom data stacks.

Does phoneveriflo reveal third-party supplier names or raw error payloads?

No. phoneveriflo operates as a strict white-label platform. All customer-facing states (queued, preparing, verifying, finalising, completed), error codes, and result schemas are standardized and provider-neutral.

What pricing model is used across solutions?

All accounts use integer USD micros (1 USD = 1,000,000 µUSD) with transparent volume tiers. Quotes are frozen at preflight, reserved atomically, and reconciled upon job completion with zero floating-point rounding errors.

Can I run verification jobs via bulk file upload and API simultaneously?

Yes. Both interfaces share the same underlying verification engine, tenant cache, pricing tiers, and double-entry ledger.

How do I get started with a specific solution?

Create a free account to access the workspace, run a free preflight scan on your test dataset, and explore the interactive documentation and integration guides.
