The front desk protects the calendar
The company's public number goes to the switchboard. Whoever answers was trained to filter out salespeople. Your SDR spends their best pitch on someone who can't buy.
B2B decision-maker phones
Decision-maker phones validated with the carrier.
Mobile numbers of company directors, managers and partners, checked with a real-time HLR lookup directly with the carrier. Every number comes with line status and contact ranking. Your team dials knowing what to expect.

The problem
Calling the company isn't calling the decision-maker.
A good decision-maker phone has two qualities: it belongs to the right person and it's active today. A regular list of company phones guarantees neither.
The number got old
People change SIM cards, carriers and jobs. A canceled line stays alive in the spreadsheet for months. Every “number doesn't exist” is one less minute in your team's day.
Without status, everything weighs the same
If nobody knows which lines work, the team calls all of them in the same order. The dead number takes the slot of a director who would have answered.
Phone validation with the carrier
HLR lookup: the carrier confirms before you dial.
What HLR is, in plain terms
HLR stands for Home Location Register. In mobile networks, it's the central register where the carrier keeps the status of each number: whether it exists, whether it's active and which network it belongs to.
An HLR lookup asks that question directly to the carrier, in real time. The decision-maker's phone doesn't ring and no message is sent. It's a technical check, not a call.
On Unique, you turn on Phone Validation via HLR in the database preferences. The carrier's answer becomes two pieces of information the team uses every day: line status and contact ranking.
Why it matters: the status comes from the source that controls the line, not from an old record. It's the difference between thinking the number works and knowing it does.

Status and ranking
Line status and contact ranking, explained.
Two labels, two questions. Status answers whether you can call. Ranking answers where to start.
Line status
The result of the carrier lookup.
| Status | What it means | What to do |
|---|---|---|
| Active — receives calls | The line is active and accepts voice calls. | It goes into the dialer queue. Start with the highest rankings. |
| Unavailable for calls, active on WhatsApp | The voice call doesn't go through, but the number has active WhatsApp. | Reach out via WhatsApp, with a short message and the reason for contact. Remove it from the dialer. |
| Inactive — doesn't receive calls | The line doesn't receive calls. | Leave it out of the mailing list and look for another number for the same decision-maker. |
| Unavailable for calls and no WhatsApp | Doesn't accept voice calls and has no WhatsApp. | Drop the phone for this contact. Use the decision-maker's email and LinkedIn. |
In the company profile, each number shows its status in a colored bar just below. When it can't be checked, it shows “Line unavailable for carrier verification”.
Contact ranking
Each number's score, in five levels.
| Level | How to use it |
|---|---|
| Very High | First hour of the day. These are the strongest numbers in the database. |
| High | Main block of the calling cadence. |
| Medium | After the high ones. Confirm at the start of the conversation that you're talking to the right person. |
| Low | When there's no better option for that decision-maker. Combine with email. |
| Inactive | Out of dialing. |
Active line and high ranking: this is the first call of the day.PRIORITY

FAQ
Questions about decision-maker phones.
What is a decision-maker phone?
It's the number of the person with purchasing power inside the company: partners, C-level, directors and managers. On Unique, you reach it by filtering by title, department and hierarchy level, instead of calling the switchboard and asking to be transferred.
What is an HLR lookup?
It's a query to the mobile carrier's central register, the Home Location Register. The answer shows the line's status in real time, without the phone ringing and without sending a message. On Unique, Phone Validation via HLR is done directly with the carrier.
What's the difference between line status and contact ranking?
Line status says whether the number receives calls, only works on WhatsApp or is out of use. Contact ranking is a five-level score, from Very High to Inactive, that helps decide who to call first. Both can be used as filters in the export.
Can I export only phones with an active line?
Yes. With Phone Validation via HLR turned on in the database preferences, you check which line statuses and ranking levels go into Export Leads. Whatever isn't checked stays out of the mailing list.
Does the list bring the decision-maker's mobile or just the company landline?
Both types can appear, and each number shows whether it's landline or mobile. Sources include Corp Phone / Decision-makers, with corporate and partner phones, and Google Phone, both on the PRO plan.
Do the phones comply with the LGPD?
Unique's database is B2B: company data and corporate contacts of the people who work there. Processing is aligned with the LGPD. The details are in our LGPD policy.
Can I send the phones straight to my CRM?
Yes. There's a native integration with HubSpot, Pipedrive, PipeRun and Allture, plus Webhook / API for your own systems. If you prefer, download the database or use Send to Claude to prioritize the leads.
