How this service works
Bulk phone list scrub: up to 100 US numbers per call. Per-number validity, in-service possibility, line type (mobile/landline/VoIP), SMS likelihood, carrier and timezone, plus summary counts. Clean SMS and outreach lists before sending.
Output
Returns a per-number array with validity flag, in-service possibility, line type (mobile/landline/VoIP/pager), SMS deliverability likelihood, carrier of record, and timezone. Also includes aggregate summary counts (e.g. total valid, total mobile, total SMS-capable) across the batch.
Example use cases
SMS campaign list cleanup
“Before I send out this week's promotional text, can you run all 95 numbers from our subscriber list through a batch scrub and flag which ones are invalid, out of service, or not likely to receive SMS so we don't waste sends?”
Outreach list line-type classification
“I've got a CSV of 60 leads we're about to call — can you check each number to see if it's a mobile, landline, or VoIP line, and also pull the carrier and timezone for each so our reps know when to call?”
Post-import contact validation
“We just imported 100 contacts from a trade show badge scan and the formats are all over the place — can you validate all of them, normalize the ones that are valid, and tell me which ones look like real in-service US mobile numbers?”
Technical details
Endpoint
POSThttps://numberintel.dev/v1/batch?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to process multiple phone numbers (up to 100) in one round trip rather than making individual lookups. Ideal for pre-campaign list hygiene, CRM imports, or any workflow where you need line type, SMS likelihood, carrier, and timezone across a batch in one call. Prefer this over the single-number endpoints when efficiency and throughput matter.
Side effects
- Batch exceeds 100 numbers — returns 400 error
- Non-US numbers submitted — may return low confidence or unsupported result
- Malformed number formats that cannot be parsed — marked invalid per entry
- Empty array submitted — returns 400 validation error
- Network timeout on very large batches — retry recommended
