Chrome Extensions That Find Candidate Contact Info

The shortlist at a glance, organised by the contact channel each tool does best. Free tiers, pricing, and accuracy all change often, so treat this as a snapshot at time of writing. "Where it works" describes where the extension reliably surfaces contact details.

One tool in this table does not find contact details at all. Recruiter Copilot scores each profile against your open role so you know who is worth the lookup before you spend a credit. The contact finders below then handle the reach. The two jobs are different, and the sections that follow explain each pick, where it falls short, and how the workflow fits together.

Apollo and SignalHire aim to return the full contact picture, so you get an email, sometimes a phone number, and links to other profiles in one reveal. They are the closest thing to a single tool that answers "give me every way to reach this person."

Apollo

Apollo pairs a large contact database with a Chrome extension that surfaces business emails, and sometimes phone numbers, on LinkedIn profiles and search results. Its strength is scale and export: you can pull data for whole lists and send it downstream in a few clicks. Business email accuracy is generally its most reliable field. Personal emails and phone numbers are patchier, as they are for every tool in this category.

Best for: Recruiters who want the most complete contact record per candidate and export data in volume rather than one person at a time.

SignalHire

SignalHire reveals emails and phone numbers on LinkedIn and often surfaces links to a candidate's other social profiles, which helps when you want a second channel to reach them. Like Apollo, it is most useful when you are processing many profiles and want a repeatable export step rather than manual copying.

Honest note: Bulk reveal is where free tiers run out fastest, and where the terms-of-service question below matters most. Harvesting data across many profiles at speed is exactly the pattern platforms watch for. If you go this route, keep volumes reasonable and read the legality section before you scale.

Lusha and Kaspr lead with direct-dial phone numbers for recruiters who would rather call than email. Both also return emails, but the phone is the reason to reach for them.

Lusha

Lusha reveals business emails and direct-dial phone numbers on LinkedIn profiles and pushes data into common systems, which suits recruiters who work the phone. Business email accuracy tends to be its stronger field, with phone coverage varying by market.

Best for: Recruiters who open with a call and want a direct number rather than a switchboard.

Kaspr

Kaspr focuses on phone numbers and emails with a European lean, and it positions itself around European data-protection expectations. If your candidates are mostly in Europe and you call first, it is worth a look.

Honest note: Phone numbers are the hardest field for any of these tools to keep current, since people change numbers and carriers without updating anything public. Expect a higher miss rate on phones than on emails, and confirm the number belongs to the right person before you dial.

ContactOut is strongest when a work email will not land and you need a candidate's personal address, which is common for engineers who ignore their corporate inbox.

ContactOut

ContactOut is known for personal email coverage, which is useful for tech candidates who are more responsive on a personal address than a corporate one. Click the extension on a profile and it returns the emails it has on file. It also has a search portal for finding people outside of a single profile view.

Best for: Recruiters who need a personal email when a business address is unavailable or unlikely to get a reply.

Honest note: Personal-email accuracy is lower than business-email accuracy across the board, and coverage varies by region and role. Do not treat a returned address as confirmed. Where it matters, verify before you send, and keep a second tool on hand for when the first comes up empty.

RocketReach is the pick when the candidate is not on LinkedIn at all. If you spotted them on GitHub, Stack Overflow, or a personal portfolio, a web-wide finder is what closes the gap.

RocketReach

RocketReach pulls emails and phone numbers from across the web and shows them on the profile you are viewing, so it is a solid generalist for one-off lookups when you are not tied to a single data source. That web-wide reach matters more than it used to. Developers in particular are discoverable far beyond LinkedIn: a lot of the best passive candidates are people you find through their code on GitHub, their answers on Stack Overflow, or their portfolio site, not their LinkedIn headline.

Best for: Sourcers who work across platforms and need contact details for candidates found outside LinkedIn.

Honest note: Web-wide coverage is broad but uneven. You may get a strong hit for one candidate and nothing for the next, so treat a cross-platform finder as one input, not the final word. To sharpen the sourcing step that comes first, see the complete guide to sourcing candidates.

Usually yes, but with conditions. Recruiters typically rely on legitimate interest to process professional contact data, and that basis comes with a duty to tell the candidate.

The UK regulator, the ICO, addresses this directly. If someone sets a professional-network profile to signal they are open to opportunities, they "would clearly expect those viewing their profile might use their contact details for recruitment purposes, and legitimate interests may be available. However, if they choose not to select that option, it is not reasonable to assume such an expectation." The ICO also warns that it is "unlikely to be lawful, appropriate or necessary to conduct intrusive or targeted checks of candidates on social media... (eg by using specialist software to check information that is not publicly available)" (ICO, Recruitment and selection).

There is also a timing duty. Under the EU GDPR, when you obtain someone's personal data from a source other than the person, you must inform them "within a reasonable period after obtaining the personal data, but at the latest within one month" (GDPR Article 14). In practice that means a short, honest note to a sourced candidate telling them where you got their details and why you are reaching out. This applies whether you found their email, their phone number, or a social handle.

The takeaway: a contact finder is not a free pass. It is a tool that carries a compliance obligation. Sourcing publicly signalled professional contacts for a genuine role is defensible. Harvesting non-public data or skipping the notice is where you get exposed.

Scraping public data is not a federal crime, but it can still breach a platform's terms, and that is a separate risk to your account.

The leading case is hiQ Labs v. LinkedIn. In April 2022 the Ninth Circuit found that scraping publicly available data does not, on its own, violate the Computer Fraud and Abuse Act (hiQ Labs, Inc. v. LinkedIn Corp., 9th Cir. 2022). That sounds like a green light, but it is only half the story. The dispute ended with the court treating the platform's user agreement, which bans scraping and fake accounts, as an enforceable contract, and hiQ agreed to stop scraping and delete the data it had collected (hiQ Labs v. LinkedIn case summary).

The practical read for a recruiter: collecting public data is not criminal computer fraud, yet doing it against a platform's terms can breach a contract and, more immediately, can get your own account restricted or removed. This is not unique to LinkedIn. GitHub, Stack Overflow, and most sourcing sites carry similar terms against automated harvesting. Tools that reveal a single contact on a profile you are actively viewing sit closer to normal use than tools that harvest hundreds of records in the background. If you value your account, keep volumes reasonable, avoid unattended automation, and understand that the platform, not just the law, sets the rules you are operating under.

Check two things before you install: that the permissions match the job, and that the extension is actively maintained on Chrome's current platform.

A contact finder needs access to the sites you source on to do its work. Be cautious with any extension that asks to read and change data on all websites without a clear reason, and review the publisher and reviews on the Chrome Web Store first.

Maintenance matters just as much. Chrome moved every extension to a newer platform called Manifest V3. Manifest V2 extensions were disabled for all users on all Chrome channels on July 24, 2025, and Chrome 138 was the last version to support Manifest V2. All remaining Manifest V2 extensions were removed from the Chrome Web Store on August 31, 2026, and cannot be reinstalled after that date (Chrome for Developers). The practical takeaway: an abandoned extension can simply stop working, so favor tools that ship regular updates.

A contact finder answers "what are their contact details?" It does not answer "is this the right person?" Those are two jobs, and doing them in order saves both time and credits.

Every lookup you run on the wrong candidate is a wasted credit and a wasted outreach slot. The upstream step is deciding who is worth contacting in the first place, and that is where Recruiter Copilot fits. Upload your job description once, browse LinkedIn normally, and each profile shows an AI match score with a skill-by-skill breakdown: green for matched skills, red for missing requirements, amber for nice-to-haves. You see why someone scored 85% or 62%, so you shortlist in seconds instead of reading every profile in full. Here is how Recruiter Copilot works in more detail.

Run the two in sequence. Copilot tells you who to pursue, then your contact finder gets you their email, phone, or social profile. Because Copilot scores before you spend a lookup, your contact-finder credits go to the candidates who actually fit, not to everyone who happened to appear in a search. It works with free LinkedIn accounts too, so there is nothing to migrate. Copilot is free to start, with 10 job description analyses and 25 AI verifications on the free tier and Pro at $9 per month for unlimited use.
