One of the most common questions in any of our classes is this:
When is the phrase follow up hyphenated?
One of the reasons this punctuation question is so commonly asked is that many dictionaries are no help at all. They simply list both versions: follow-up and follow up.
I am happy to offer a way to determine whether the hyphen is required. Here's how:
If you can use the word the directly in front of the words follow up, they need a hyphen. Examples:
Please give Assan the follow-up test.
Have you sent the follow-up to Marty?
Make a follow-up call tomorrow. [You could replace a with the.]
In contrast, the sentences below would not work with the word the inserted before follow up:
Please follow up with Assan by giving him the test.
Did you follow up with Marty?
Follow up by phone tomorrow.
That's all there is to it! If you use the method above, you will always know whether follow-up or follow up is correct.
Stop reading now if just knowing the "trick" is enough for you. However, if you would like to know the reason it works, along with the rules, read on.
When follow up is a verb, it has no hyphen. Since we never use the before verbs (the belongs before nouns and adjective-noun phrases), if you cannot insert the before follow up, you know the phrase is a verb. Verb = no hyphen.
When follow up is a noun or an adjective, it does need a hyphen. Examples:
Noun: They lost interest during follow-up.
Adjective: The follow-up phase dragged on too long.
Since you can easily insert the before a noun or an adjective, inserting the (if it isn't there already), tells you that your phrase needs a hyphen.
Test Yourself: Hyphen or No Hyphen?
- Please give me a follow up call next week.
- The follow up report is almost ready.
- Call Amy to follow up about the invoices.
- Omar will follow up on Friday.
- I enjoy implementation but not follow up or maintenance.
Could you recognize which sentences needed hyphens?
Answers: Hyphens in 1, 2, and 5. No hyphens in 3 and 4.
Follow up if you have a follow-up comment or question! If you are in the Seattle area (or nearby states or provinces), take our workshop The Keys to Error-Free Writing for more helpful strategies and guidance on punctuation, grammar, and usage.

Hi Lynn,
A heartfelt "Thank you" for writing this piece of information. You are God sent.

Incredibly helpful! Thank you for writing the explanation in such basic terminology that practically anyone can understand it!

Almir, Manashree, and Zach, you are all welcome! Thank you for taking the time to comment.

Hi Lynn, this article has cleared my thoughts. Thank u so much
Posted by: Pradeep Paul | July 24, 2009 at 11:05 PM
You have cleared views regarding follow-up and follow up, but how about one word followup? Please explain.
Posted by: Pradeep Paul | July 24, 2009 at 11:30 PM
Hi, Pradeep. I have not seen "followup" as one word in any style guides. However, the trend is to close up some hyphenated words after they become commonly recognized and understood. For example, "microwave" was originally "micro-wave," and "e-mail" is moving toward "email."
The noun "followup" is probably appearing, but it is not yet in any style guides on my shelf. I would avoid it, since it may confuse readers who wonder what a "wup" is.

Hi Lynn
Thanks a lot for the clarification. I was confused with so many tips, but this one is very clear.
Posted by: SVD | October 10, 2009 at 01:18 AM
Makes perfect sense!
Posted by: Zack | December 09, 2009 at 12:02 PM
This is the best advice I have seen. Thank you.
And what about followup? as one word?
Posted by: Karen | January 15, 2010 at 07:10 AM
I haven't seen "followup" as one word in a dictionary or style guide yet. When I see it, I will update this information.
Lynn
Posted by: Lynn Gaertner-Johnston | January 16, 2010 at 07:18 PM
Hi, Lynn. What about communications that begin with the prhase, "This is in follow up to...?" I can't correctly place "the" before follow up, so it would seem that no hyphen should be used. On the other hand, I could replace "in" with "a," suggesting that follow-up is a noun or adjective and is, thus, unhyphenated.
Posted by: David | January 26, 2010 at 05:22 AM
Your example is a noun. Place "the" before the phrase like this:
"This is the follow-up to . . . "

Posted by: Lynn Gaertner-Johnston | June 06, 2010 at 08:31 AM
What if it's the subject of an email such as Follow up on Issue A
Posted by: m | July 28, 2010 at 07:33 AM
Try my trick: Can you insert "the" before the word? If you can, it's a noun and needs a hyphen.
The Follow-Up on Issue A

Thanks again for clarity on a oft-used business term.
Posted by: Jerry Everett | August 30, 2010 at 08:22 AM
So, in this case:
"Barry's highly anticipated follow up to 2009's smash hit will be released soon." the hyphen is NOT needed? It feels like it needs a hyphen.
Posted by: rehana | September 02, 2010 at 07:23 AM
Rehana, you are right. It needs a hyphen. "The highly anticipated follow-up...."
Lynn
Posted by: Lynn Gaertner-Johnston | September 02, 2010 at 02:21 PM
Hi Lynn. Could you help to clarify when,where and why "Apostrophe" to be used in sentences like "She should follow up in a month's time or she should follow up in 3 months' time". What are the guidelines?
Posted by: Samik | September 07, 2010 at 09:08 AM
Samik, I have written about your topic. See the Search box at the top right on this page? Type this phrase in it:
Years' or Year's or Years
You will find the explanation in that post.

This has been very helpful. We write a report an we call it "The Audit Follow-up Report"
My question is, should "Up" be capitalized? Follow-Up or Follow-up?
Kind regards,
Amar

Hi, Amar. Please search for my blog post called "Capitalizing Hyphenated Words in Titles." In it, I discuss your question.

In medical transcription they have omitted follow-up and use it as one word followup but the rules apply as if you use follow-up.
Posted by: Naomi | October 24, 2010 at 07:17 PM
Hi, Naomi. So a nurse would make a followup appointment and then follow up with the patient?
I am not surprised to learn that the word is beginning to be closed up.
Lynn
Posted by: Lynn Gaertner-Johnston | October 24, 2010 at 08:02 PM
Thanks very much Lyn for your explanations. I'd like to know if I should say follow up to or follow up on something.
Thanks, Adjoa
Posted by: Adjoa des Bordes | February 04, 2011 at 12:37 AM
Hi, Adjoa. Typically the correct expression is "follow up on."
Examples:
I want to follow up on what we discussed.
Did you follow up on Dina's request?
There are circumstances in which "follow up to" is more suitable. Here is an example:
Will there be any follow-up to the training program?
I hope those examples help you.
Lynn
Posted by: Lynn Gaertner-Johnston | February 04, 2011 at 02:38 PM
Hello,
I am a court reporter and have this phrase come up almost everyday.
1- They recommend follow up visits.
2- I had follow ups.
Should these "follow up" phrases be hyphenated?
Thank You
Posted by: Amanda | February 18, 2011 at 07:59 AM
Hi, Amanda. Your examples are similar to those I shared above in the post.
In sentence 1, the term is an adjective. In sentence 2, it is a noun.
Both examples need a hyphen.
Lynn
Posted by: Lynn Gaertner-Johnston | February 18, 2011 at 09:24 PM
I'm a medical transcriptionist.
Follow-up = adjective, as in "follow-up care."
Follow up = verb, as in "will follow up tomorrow."
Followup = noun, as in "will be seen in followup."
Unfortunately, even most medical transcriptionists get it wrong. :)
Posted by: Pat | June 12, 2011 at 07:13 PM
Hi, Pat. Nearly all my reference books are still showing the noun form with a hyphen. I wonder which style manual you follow. If you see this comment, please let me know.
Lynn

Thank you for this article, Lynn. It was very helpful.
Posted by: Kathleen Jo | July 11, 2011 at 12:23 PM
Lynn, I am so glad that I stumbled upon your blog, I appreciate your help and knowledge. I was wondering if this rule applies to the word "pick up". I'm not sure if it is suppose to be one word, two words, or a hyphenated phrase.
Thanks again!
- Sandy
Posted by: Sandy | July 13, 2011 at 10:49 AM
Hi, Sandy. The rendering of your word depends on how you will use it.
Pick-up. A noun describing a person or thing picked up or increasing:
"We are pleased about the pick-up in business."
"I have a pick-up to make downtown before I end my shift."
Pick up. A verb:
"We are pleased that our business has picked up."
"I have to pick up a passenger downtown before I end my shift."
Pickup. An adjective meaning "informally organized":
"He likes to participate in basketball pickup games."
Sandy, if your budget includes money for a current dictionary, I recommend getting one. It will answer many of your questions. If you live in the U.S., I recommend "Merriam Webster's Collegiate Dictionary" and "The American Heritage College Dictionary."
If you live in Canada, I recommend "Canadian Oxford Dictionary."
Reference books will not necessarily agree on the rendering of your word or other words. I just checked my "Canadian Oxford Dictionary" and found "pickup" for the noun version. Nevertheless, a current dictionary will guide you in your choices.

Can you pls let me know how to say

Posted by: aida | October 10, 2011 at 10:36 PM
Aida, here are several correct ways:
Mr. George is following it up daily.
OR:
Mr. George follows it up daily.
OR:
Mr. George follows up daily.

Very clear explanation. Thanks for this article.
Posted by: Padmapriya | October 21, 2011 at 12:45 AM
In my experience, the hyphenated form should be reserved for use of the term as an adjective, but not a noun.
Posted by: Christian Hesketh | December 08, 2011 at 03:21 PM
Hi, Christian. Do your reference manuals support your experience?

Thank you for the article. I just used it to change my incorrect "a follow up bet" to "a follow-up bet" in my own article. I had a feeling something was wrong, but obviously spell check wasn't helping.

Yes, Jonathan, you are now correct. I am glad to have been helpful.

Yes, this is what I was looking for. If I wasn't curious to know, I would have spelled follow-up incorrectly half the time.

Posted by: Arocha Christine Vivian | July 11, 2012 at 02:10 AM
I am not sure what you want to accomplish with each call. Of course, you will begin with your name and company name, then the reason for your call.
Good luck!
