BUILT AROUND CALL-CENTER PLANNING
Explore our country libraries and compare field structures for your internal telemarketing plans. Define the market, audience, and information your agents need before choosing a package.
Discuss the calling-list requirements of your client campaigns with us. Keep each client’s data specification, access permissions, and suppression process clearly documented.
Compare country options and plan data requirements around your campaign brief. Package suitability depends on coverage, available fields, freshness information, and the intended calling method.
KNOW WHAT YOU ARE IMPORTING
We help you assess a phone number library as an input to your calling workflow. A large record count alone does not explain whether the data fits your market, platform, or campaign.
Start with the phone-number field, then confirm country codes, number types, and any supporting attributes. Ask us for the actual package specification rather than assuming every country library has identical fields.
| Field | What to confirm with us |
|---|---|
| Phone number | Availability, format, and whether the package contains mobile numbers, landlines, or a mixture. |
| Country code | Whether supplied separately or within the phone-number field. |
| Location | Available country, region, or city fields and how they were assigned. |
| Contact name | Whether included and the completeness of the field. |
| Source information | Package-specific source categories and available supporting documentation. |
| Update information | Whether a date refers to collection, maintenance, or a defined validation check. |
Field availability varies. A phone country code does not, by itself, establish current residence or the appropriate calling time.
A SIMPLE PLANNING PROCESS
A CALLING LIST IS ONLY THE STARTING POINT
We organize this library directory around the questions call-center teams need to resolve before ordering. Our focus is on the country package, its available fields, and the information needed to assess its suitability.
Confirm how international prefixes, country codes, and leading zeros are represented. Preserve phone fields as text during import to avoid losing meaningful characters.
Ask us how duplicates are defined for your package. Normalize formats consistently, then check overlap against your existing CRM records and previous campaign files.
Request the available collection, update, or check date. Number ownership and service status can change, so a historical check should not be treated as a live connection guarantee.
If an accuracy figure is discussed for a package, ask us which attribute it measures. The definition, test date, sample size, exclusions, and error categories matter. A formatting pass rate is different from a live connection rate or sales conversion rate.
Phone validation and permission to call are separate checks. Purchasing a library does not itself establish recipient permission or remove campaign-specific restrictions.
Before outreach, assess applicable do-not-call and internal suppression requirements, calling hours, caller identification, and the rules relevant to your calling method. Requirements can differ between manual, automated, and prerecorded calls.
For US campaign planning, consult the FTC’s Telemarketing Sales Rule guidance. Other destinations require their own review. We do not present our library as automatic approval for a campaign.

QUESTIONS BEFORE YOUR NEXT CAMPAIGN
Explore the practical details before selecting a phone number library for your call center.
Contact Our Team →Our phone number library organizes country-specific phone data options for teams planning telemarketing campaigns. Start with the market you want to call, then confirm the package fields, record volume, update information, and permitted use with us.
Use our country directory above to open the available library pages. A listed country page is a starting point; contact us to confirm current package availability and coverage before ordering.
Number types can vary by package. Ask us whether your chosen library contains mobile numbers, landlines, a mixture, or a documented line-type field. Do not assume every telephone number supports every channel.
Phone numbers are the core field to confirm. Names, location attributes, source information, and update details may vary. Request the actual specification for the library you intend to purchase.
Contact us about sample availability for your selected country library. Use the sample to inspect number formatting, field names, missing values, and suitability for your import workflow.
Confirm the available file format with us before ordering. Tell us whether your workflow needs CSV, TXT, or another supported format, and discuss column structure and encoding requirements.
Compatibility depends on your platform and its import requirements. Compare our available file specification with your system documentation. We do not imply a direct integration or guaranteed compatibility with every platform.
Ask us about the duplicate definition and handling applied to your chosen package. Normalize number formats before checking your own files, and assess overlap with previous purchases and existing CRM records.
Contact us for the available collection, update, or check date for the selected package. A webpage publication date is separate from a phone record’s last check date.
Confirm which screening, if any, applies to your package, its date, and its jurisdiction. Your call-center process should separately address relevant national registries, internal suppression lists, objections, and campaign-specific restrictions.
No. Purchasing our data does not itself establish permission for a telemarketing call. Assess the applicable rules for the destination, recipient, purpose, and calling method before loading a campaign.
