How to ask for a job referral on LinkedIn
LinkedIn decides what you're allowed to send before you decide what to say. Learn the three channels and the limits on each, and the wording follows from them.
By Jerry Feng, Growth at Happenstance. Updated August 28, 2026.
The short version
Your connection degree decides which message you're allowed to send, so check it first. If you're already connected, message them and put the requisition in the opening line. If you're not, send a connection request with a note, which LinkedIn limits to 200 characters on a free account and 300 on Premium, and keep the referral ask out of that note: the note buys the connection, the message that follows makes the ask. Name the person you both know rather than the number of people.
What LinkedIn gives you free, and what it charges for
There are three channels, and the site decides which one you get. First-degree connections can be messaged directly. Everybody else has to be invited to connect, with or without a note, or reached by paid InMail.
The note is where most job seekers get stuck. It is capped at 200 characters on a free account and 300 on Premium. LinkedIn's help page says “Members with basic (free) accounts can send up to five personalized invitations to connect with a character limit of 200. Members with Premium memberships are able to send an unlimited number of personalized notes with their invitation/connection requests each with a character limit of 300”. Write to 200 characters and spend the notes carefully.
InMail has a catch. The same help page describes it as “a premium feature” for messaging members you aren't connected to, and adds that “You can't message a member if they've chosen not to receive InMail messages in their message preferences settings”. So paying does not guarantee you can reach somebody.
LinkedIn can only show you ties that exist on LinkedIn. Somebody you emailed weekly for three years but never connected with there is invisible to every filter on the site, even if they now work at the company you want. For anybody more than a few years into a career that is a large gap, which is why the search step belongs off the platform.
Doing this with Happenstance
Finding who else could vouch for you is what LinkedIn can't help with, because it's a question about the network LinkedIn does not hold. Happenstance builds one network from seven connected accounts: Gmail, Outlook, Google Calendar, Google Contacts, LinkedIn, Twitter and Instagram. LinkedIn is one of the seven, so its connections are in there, sitting next to the people you only ever emailed. Ask “Who do I know at Figma that is not on my LinkedIn?” and you get the names, their current title and which account the relationship came from.
Happenstance is free. The free plan is the whole product, with usage limits on chat and web searches beyond your network. Pro raises the limits: unlimited web searches and results, higher chat limits, and CSV export. Mutual connections covers what LinkedIn's shared-connections count leaves out, and Happenstance for job seekers is the search run over a whole job hunt.
Three messages, sized for their channel
One per channel. The note is 171 characters with the brackets still in it, which leaves room for real names.
Template 1: the connection note, 200 characters
Template 2: the message after they accept, or to a first-degree connection
Subject: The [staff engineer role] on your team
Template 3: InMail, where there's no other route
Subject: [Ben Ito] suggested I write, about the [staff engineer role]
Off LinkedIn, where you have room to write properly, the fuller version of the ask is on how to ask for a referral for a job, and asking someone to refer you covers the case where the tie is old enough that the message has to do more work.
What Happenstance can see
Email is read as headers only. Message content and attachments never reach our servers. Yes. Your connections are searchable only by you, the friends you accept, and the groups you join, and sharing is always mutual. Your public profile shows a constellation of named people you know by default, which you can turn off anytime. We never share, sell, or use your data to train AI models. Happenstance is SOC 2 certified and DTI Trust Level 2; the full list of what is stored and for how long is on the security page.
Frequently asked questions
How many characters can a LinkedIn connection request note be?
200 characters on a free account and 300 on Premium. Free accounts also get only a few personalized notes a month, while Premium members can send an unlimited number. Write to 200 and spend the notes on the people who matter.
Can you ask for a referral on LinkedIn?
Yes, and for a first-degree connection it's a normal use of the messaging feature. What doesn't work is asking inside a connection request note, because a stranger is being asked to accept you and vouch for you in the same 200 characters. Connect first, then ask in a message where you've room to name the requisition and what they would be vouching for.
Should I connect first or send an InMail?
Connect first. InMail is a paid feature that reaches people you are not connected to, and LinkedIn's own help notes that a member can switch InMail off in their message preferences, in which case the credit isn't even an option. A connection request costs nothing and, if it's accepted, gives you an ordinary conversation rather than a sales channel.
Does having a mutual connection help on LinkedIn?
It helps when you name the person and what they're to both of you. LinkedIn shows a shared-connections count on profiles, and a count is not evidence of anything. One named person and one line about the work you did together does the job the count cannot, because it gives the reader somebody they can go and ask about you.
Will they see that I looked at their profile first?
Only if your profile-viewing setting is the default, which records your name and headline in their viewers list. In private mode you appear as an anonymous viewer, and you give up your own viewer data in return. Being seen looking at somebody's profile shortly before you write to them isn't a problem; it reads as ordinary diligence.
How do I find jobs where I already know someone?
LinkedIn has a "Hiring in your network" filter on job search and a "Meet the Hiring Team" module on job detail pages, and it notifies members when a first- or second-degree connection is hiring for a relevant job. Those only surface ties that exist on LinkedIn, so treat them as one input rather than a full picture of who you know at a company.
