WHAT EACH CHECK CAN RETURN

Six ways to understand a phone number.

Field availability can vary by number, country and data source.

01

Phone number validation

Check number structure and validation signals. Get a result you can use to accept, correct or review a contact.

Try the phone validator
02

Line type detection

Distinguish mobile, landline, VoIP, toll-free and premium-rate numbers before choosing a contact channel.

Check a line type
03

Carrier lookup

Add available carrier information to your phone records for routing and segmentation.

Look up a carrier
04

Consistent number formats

Standardize numbers into E.164 format to make contact data easier to store and use.

Check number format
05

Country and region

Identify numbering location and timezone where available. This does not track a person’s physical location.

Explore location data
06

Risk signals

Review number-related warning signs alongside your own checks. A VoIP number alone does not mean fraud.

Understand risk scores
READ THE RESULT

Validity and risk answer different questions.

Keep validation status, line type and risk signals separate when making decisions.

01Valid

The number passes the available validation checks. This does not confirm ownership or guarantee delivery.

02Invalid

The number fails available checks. Ask the person to correct it or review the record before outreach.

03Risky

The result includes warning signs worth reviewing. A valid number may still warrant an additional check.

PRIVACY & RESPONSIBLE USE

Clear data practices. Clear responsibilities.

Review how SPV describes customer-data processing before introducing it into your workflow.

CUSTOMER DATA

Your numbers.
Your processing purpose.

SPV’s published policy states it processes submitted data to deliver the requested service and does not sell submitted personal information.

Read the privacy policy

Privacy and data protection

The policy addresses GDPR and UK GDPR, data-subject rights and international transfers. Customers remain responsible for their lawful basis for processing.

Retention and security

Retention varies by purpose and legal requirements. Review the published policy and ask the team for retention periods and the controls relevant to your deployment.

Validation and outreach consent

A valid number does not establish permission to call or text. Apply your consent, suppression and channel-specific checks separately.

FREQUENTLY ASKED QUESTIONS

Direct answers to your questions.

Find the practical details for this page.

Which fields can SPV return?

Validity, standardized formats, line type, carrier, location, timezone and risk fields. Availability can vary by number and country.

Does a location field track the phone owner?

No. It describes number-associated geographic context, not current physical location.

Does formatting prove a number is active?

No. A well-formed number is not by itself evidence of current service or reachability.

Can a valid number still have a risk flag?

Yes. Validity and risk answer different questions. Read the reason and apply your own review policy.

Can I check numbers through my dashboard?

Yes. The dashboard has single lookups, bulk CSV uploads, and a history of your lookups and bulk jobs.

Will the same details be available worldwide?

Not necessarily. Test the countries and fields required for your workflow.
