# Check if a phone number is live

Provider: HLR Lookup
Final price: $0.013216/success
Success rate: n/a

Performs a live HLR lookup, returning number type, live status, original and current network, and porting information. Warning: a national number sent without input_format can be read as another country's number (a US 617... number as an Australian 61... number), and that lookup is still charged.

## Parameters

- usa_status (string, optional)
- input_format (string, optional)
- output_format (string, optional)
- save_to_cache (string, required)
- telephone_number (string, required)
- cache_days_global (integer, required)
- cache_days_private (integer, required)

## Example

```curl
curl -X POST 'https://toolswitch.dev/v1/tools/hlrlookup.people.phone.verify' \
  -H "X-Toolswitch-Key: $TOOLSWITCH_KEY" \
  -H "Content-Type: application/json" \
  --data-raw '{"save_to_cache":"PRIVATE","telephone_number":"447540822872","cache_days_global":0,"cache_days_private":0}'
