Glossary

Understand verification terms before you build policy around them.

Technical and operations teams use the same words differently. This glossary defines how phoneveriflo uses important data-quality, API, cache, and workflow terms.

What you need to know

Core data terms

Use these definitions consistently across UI, docs, exports, and support.

E.164

An international phone-number representation beginning with + and country code. Formatting alone is not validation.

Normalized input

A cleaned representation used for matching, deduplication, and supported verification workflows.

Exact duplicate

The same normalized value appearing more than once in the relevant preflight scope.

External ID

A customer-supplied row or record identifier used to reconcile results back to the source system.

Verification and freshness terms

Make time and uncertainty explicit.

Fresh check

A request the phoneveriflo job sends for new processing rather than serving an eligible phoneveriflo cache entry.

Cache hit

A reusable result found under the configured service/schema/scope and still inside its TTL.

Checked at

The timestamp when the underlying result was originally produced.

TTL

Time-to-live: how long an eligible cached result may be reused under the configured policy, capped at 90 days in this application.

Network metadata terms

Carrier and line-type fields are metadata returned by supported lookup services; they are not identity or ownership proof.

API workflow terms

Idempotency prevents accidental duplicate writes; a webhook is a signed server-to-server event; a job is the first-party asynchronous unit of work; a normalized result is the customer-facing schema independent of the upstream provider.

FAQ

Questions about glossary

Is E.164 the same as a valid phone number?

No. It describes formatting/representation, not reachability, ownership, or current service status.

Does cached mean inaccurate?

No. It means the result was originally checked earlier and is being reused within a configured TTL. The checked time should always remain visible.

What is a line type?

A network classification such as mobile or landline when returned by a supported carrier lookup.

What is idempotency?

A request-safety pattern that allows a client to retry a write without unintentionally creating duplicate work when supported by the API.
