International numbers.
One validation workflow.
SmartPhoneValidator publishes coverage for 248+ countries and territories. Available validation and enrichment fields can vary by market.

A coverage count does not mean every field is available everywhere.

Number structure
Use the country code and the market’s numbering conventions when preparing input.
National input should include an unambiguous country context.
- 02
Carrier and line type
Availability can depend on country, number type and data source.
Test representative numbers before building routing rules.
- 03
Location and portability
Interpret regional and carrier details as available number data rather than a person’s live whereabouts.
Ask the team about current portability handling for your markets.
Test your workflow before scaling.

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

How many countries does SPV cover?
Numbers from 248+ countries and territories can be validated. Field availability varies, so confirm the fields needed in your specific market.
Are carrier details available for every number?
No universal availability is established. Carrier details depend on the number, market and data source.
How do I evaluate a new market?
Test representative numbers and inspect the returned fields before scaling. Ask the team about your specific requirements.
Should I include a country code?
Use an international number with its country calling code to remove ambiguity.
Does regional data show where someone is now?
No. It represents number-associated geographic information, not live device tracking.
Where can I find the full country list?
On this page. Search by country name or dial code, then open a country to see its dial code, number formats and what each check returns.
Start with the numbers you have.
Check a single number, clean a contact list, or add validation to your app.
