Run large verification jobs without losing control of cost or progress.
Bulk verification in phoneveriflo is a staged workflow: prepare data, preflight the job, freeze the quote, process only what needs work, and export first-party results.
The six-step bulk workflow
The interface should make every stage visible rather than presenting a single opaque loading screen.
1. Upload a supported file or paste a smaller set of values.
2. Map the phone/email and optional external-ID columns.
3. Run preflight to identify invalid formatting, duplicates, cache hits, and fresh work.
4. Review and approve the frozen maximum quote.
5. Process the job through the queue with visible status.
6. Export normalized results or consume them through the API/webhooks.
Preflight reduces avoidable spend
The Preflight Ledger is the core conversion and trust element of the product.
Uploaded row count.
Invalid-format count.
Exact duplicate count.
Eligible cached count with freshness policy.
Fresh checks required.
Estimated and maximum charge before the customer commits.
Designed for operational reliability
Large jobs should be chunked, retried safely, and observed without leaking provider implementation details.
Queue visibility
Show queued, processing, completed, failed, and retrying states with timestamps.
Partial failure handling
Keep row-level issues separate from whole-job failure and make retry behavior explicit.
Exports
Deliver normalized CSV/JSON results with stable customer-facing fields.
Automation
Use API jobs and signed webhook events when the workflow must run without manual UI steps.
What bulk verification does not promise
A bulk workflow coordinates supported verification services. It does not convert an underlying signal into proof of identity, guaranteed message delivery, or a fraud verdict.
Questions about bulk verification
What file types are supported?
The current product design supports CSV/TXT-oriented bulk input. Exact size and row limits should be configured from the production service policy and shown in the upload UI.
Why is the quote frozen?
It gives the customer a deterministic maximum price for the confirmed job composition during the quote window.
What happens to duplicate rows?
Exact duplicates can be excluded from fresh processing according to the preflight rules while preserving row-level output mapping.
Can I automate bulk jobs?
Yes. The customer API and webhooks are designed around asynchronous job creation and status/result delivery.
