As investigators, it’s not just about what we gather; it’s about our capacity to breathe life into that data, to unravel its stories, and to make informed decisions that drive investigations to their rightful conclusions. To begin, let’s delve into the meanings behind some of the information you might gather during your investigation of an international phone number.

Country of Origin: Above all else, always check the country of the phone number first even if you are 99% sure. I employ the number analysis tool provided by International Numbering Plans to carry out this identification process.

Phone Number Validity: Let’s proceed with the verification of this number and what “valid” actually means. Valid” in this context solely refers to the correctness of the number’s format, without confirming its active. To perform an actual validation and ascertain the real existence of a mobile number, an approach worth considering is the utilization of an age-old technique known as Home Location Register (HLR) lookups. “HLR” stands for “Home Location Register.” The HLR houses crucial subscriber-related information encompassing personal particulars like name, contact details, and address; essential authentication and network access data including IMSI and Ki; status of the subscriber’s account, whether active, suspended, or terminated; the latest network location of the subscriber; specifics of services and features linked to the account, spanning voice, data, SMS, etc.; and indication of ongoing roaming on external networks.

Ported & Roaming: If you observe that the number is ported, it means that the number has been transferred or moved from one telecommunications service provider to another. Porting allows individuals or businesses to retain their existing phone numbers even if they switch to a different mobile network operator or landline provider. This process is known as “number portability.” Roaming is a service provided by mobile network operators that allows a mobile device, such as a cell phone or tablet, to connect to and use another network, typically when the device is outside its home network’s coverage area. This enables users to make calls, send texts, and use mobile data even when they are in a different geographical location, whether it’s within their own country or when traveling internationally.

Carrier: A mobile carrier furnishes crucial insights to investigators examining a phone number. This includes network identification, disclosing the specific mobile network provider associated with the number, aiding in understanding its technical infrastructure. The carrier’s identity can also shed light on the geographic context, helping to infer the likely region or country of the number. Furthermore, it provides information about service availability, potential for roaming, network technology employed (e.g., 2G, 3G, 4G, 5G), and even the quality of service and user demographics associated with the carrier. Investigating the carrier’s reputation can offer a comprehensive view of user experience. Additionally, the carrier’s details might reveal fraud or scam indicators, and understanding its regulatory and legal context can be pivotal in comprehending the number’s usage and implications.

Mobile or Landline: Knowing whether a phone number corresponds to a mobile or landline connection offers investigators crucial contextual information. This distinction aids in determining the likely type of user or entity associated with the number. Mobile numbers are often tied to individuals and personal devices, potentially facilitating more direct and personal communication. In contrast, landline numbers are frequently associated with businesses or fixed locations, suggesting a professional or organizational context. This knowledge enables investigators to tailor their approach, anticipate the nature of interactions, and make more informed judgments about the purpose and significance of the number in their investigative efforts.

“Open” Phone Number: In the context of OSINT (Open Source Intelligence), an “open phone” typically refers to a mobile phone number or device that is accessible and actively used in online or digital contexts. When an investigator encounters an “open phone” during OSINT activities, it signifies that the phone number is publicly available, visible, or openly shared on the internet or various online platforms. This information can be valuable for investigators because an open phone number provides an avenue for communication and interaction, enabling potential outreach, verification, or tracking of an individual or entity associated with that number. It can serve as a starting point for further investigation, such as verifying identities, establishing connections, or uncovering additional information through social media profiles, online directories, or other digital footprints.

Network Type: When conducting OSINT investigations, the distinction between network types such as CDMA (Code Division Multiple Access) and GSM (Global System for Mobile Communications) holds significant relevance for investigators. It aids in identifying the specific mobile communication technology a device utilizes, determining carrier compatibility and potential ownership, considering geographical factors and roaming possibilities, assessing device compatibility, understanding communication patterns, and even delving into privacy and security implications. This knowledge allows investigators to glean insights into the device’s operational framework, potential locations, carrier associations, and user behavior, enhancing their overall investigative understanding.

International & Local Format: As your investigative journey progresses, the significance of possessing both the international and local formats of a phone number becomes increasingly pronounced. This dual-format approach evolves into an indispensable tool, gaining prominence as you navigate deeper layers of your search and strategically deploy an arsenal of investigative tools at your disposal. The international format, with its inclusion of the country code, stands as a beacon of global context, swiftly illuminating the geographical origin of the phone number and allowing you to align your investigative trajectory accordingly. In tandem, the local format brings the number to a level of familiarity within the localized context, affording you the capacity to harmonize your efforts with localized sources and platforms.

Importance of Language: When confronted with the task of searching for a non-English phone number, it’s imperative to adapt your approach to maximize effectiveness. Firstly, harness the power of relevant keywords and operators in the local language associated with the number. This strategic maneuver aligns your search with the linguistic nuances that are likely to yield more accurate results. Additionally, expanding your toolkit to encompass country-specific search engines can be a game-changer. These specialized engines are finely tuned to the nuances of the local web, rendering your search efforts more tailored and yielding outcomes that are contextually relevant. By seamlessly blending linguistic accuracy with platform precision, you can embark on a more fruitful search for information tied to non-English phone numbers.\

Using a VPN: Leveraging a Virtual Private Network (VPN) with a local IP for your OSINT Google searches can yield multifaceted benefits. Firstly, it enables access to localized content that might be concealed in search results based on geographical location. Additionally, a local IP enhances the chances of encountering region-specific content, as Google’s algorithms often prioritize search outcomes in the local language or tailored to the country’s context. Furthermore, a VPN with a local IP can surmount geo-blocking obstacles, allowing access to crucial information from websites restricted by geographical boundaries. In regions with content filters or censorship, a VPN can be instrumental in evading these restrictions and obtaining vital data. However, it’s pivotal to meticulously assess the VPN service’s quality, navigate legal and ethical considerations, safeguard data privacy, recognize the persistence of search personalization, and gauge the potential impact on information accuracy. Ultimately, the decision to adopt a VPN with a local IP should be thoughtfully made, aligning with your investigation’s objectives and ethical framework.

Boolean Search Method

How? It comes down to how you do it. Using the Boolean search method to gather information on an international phone number involves creating precise search queries using operators to filter and refine search results. I consistently conduct an online search to determine the appropriate international format for the specific country, ensuring that I locate the correct format to utilize. Craft a search query using Boolean operators and relevant keywords. Start with the phone number in international format, including the country code. For example: “international phone number” OR “phone number format” AND “COUNTRY NAME” OR “COUNTRY CODE” OR “AREA CODE”

Customize the query by replacing “COUNTRY NAME,” “COUNTRY CODE,” and “AREA CODE” with the actual country details associated with the phone number. Modify your query using different combinations of keywords, Boolean operators, and parentheses to cover various aspects.

For example:

• Include the phone number in different formats.
• Include common variations of the country name or code.
• Search for mentions of the number on different platforms.

Social Media & Mobile Applications

When embarking on the exploration of mobile applications and social media platforms, it’s imperative to bear in mind a comprehensive approach.
