Real estate investors and wholesalers
Phone list checks for real estate investors
A skip trace gives you several numbers for each owner, and some are landlines or out of service. Upload the list and every number comes back textable, callable, invalid or unknown, so texts go to mobile lines and callers skip the dead ones. Unknown results and duplicate rows cost nothing.
Upload a listWhat you get
What you get back
Every field below is in the API response, with the type to expect.
| Field | Type | What it means |
|---|---|---|
valid | boolean | Whether the number can be a real one. This is a format and numbering check, not proof that anyone answers. |
verdict | string | The short answer for the row: textable, callable, invalid or unknown. |
reason | string | Why the verdict is what it is, such as mobile, bad_format or outside_coverage. |
line_type | string | null | The kind of line: mobile, fixed_line, voip, toll_free and the other types a carrier reports. null when unknown. |
voip | boolean | true for an internet (VoIP) number. Texting one is unreliable. |
carrier | string | null | The carrier that holds the number, as our data source names it. |
Verdicts
A verdict for every row
Read the verdict first. The reason field says how we got there.
| Verdict | What it means | What to do with the row |
|---|---|---|
| Valid · Mobile | A mobile number. It can be called and texted. | Keep it. Whether you may text it depends on consent, and this check does not look at consent. |
| Valid · Landline | A line that can be called: a landline, a toll-free number, VoIP or another type. A VoIP number is flagged because texting it is unreliable. | Call it. Do not count on texts, and send VoIP rows to your call list. |
| Invalid | Not a working number. It is not a real phone number, or no carrier holds its exchange. | Drop the row. If the number looks like a typo, fix it and check it again. |
| Unknown | We could not tell what the number is. You are not charged. | Set the row aside and check it again later if it matters. |
Verdicts describe reachability. They are not compliance checks.
How it works
How it works
Four steps, and none of them needs a call with us.
- Step 1
Upload a CSV
Drop in a CSV file. We read the header row and look for the column that holds the phone numbers.
- Step 2
Confirm the column
We pick the phone column and show a few values from it. Change it if we guessed wrong.
- Step 3
See the cost before you pay
You see how many unique rows there are and what they cost against your balance. Duplicates and empty rows are free, and nothing is taken until you confirm.
- Step 4
Download by verdict
Get the full file plus one file per verdict. Rows that come back unknown are returned to your balance, and we email you when it is done.
Limits
What this check cannot tell you
Knowing where a check stops is what lets you trust the part that works.
- Live data covers numbers in the United States and Canada. A valid number anywhere else gets a format check, the verdict unknown and no charge.
- Carrier answers are cached, so a number that changed carrier very recently may still show the old one.
- We do not say who owns a number. A carrier is a company, not a person, and we do not look people up.
- A number that was real once and is now out of service can still come back callable. A carrier lookup shows what kind of line a number is, not whether anyone picks up.
- Verdicts do not cover consent or Do Not Call lists. Whether you may contact a number is a separate question that this check does not answer.
FAQ
Questions about this check
Short answers. If yours is not here, write to support@numberlookup.io.
Does textable mean I am allowed to text the number?
No. Textable means the number is a mobile line that can receive a text. Whether you may text it depends on consent and on the Do Not Call rules that apply to you. We do not check either, so keep doing that yourself. If you are unsure, ask a lawyer.
Can you tell me who owns a number?
No. We return the line type, the carrier and the region, and nothing about the person or business behind the number. A carrier is the company that holds the number, not the person who uses it. We do not offer name lookups or reverse lookups.
What am I charged when a result is unknown?
Nothing. A result of unknown costs 0 credits. So does input that is not a phone number at all, an empty row and any error. In a bulk list, duplicate rows are free, and rows that come back unknown are returned to your balance when the list finishes.
Do credits expire?
No. Credits from a pack never expire, credits from a plan never expire, and neither do the free credits you get at sign-up. If you cancel a plan, the credits already on your account stay there.
