1. The system doesn’t recognize my user name/ACS ID.
We can send you your user name and a new password to access your account. If you know the email address you used to register, go to Forgot User Name/Password.

Or, contact Customer Service:

  • Email
  • Phone: 800-227-5558 (US only) or 202-872-4600 (outside the US). Hours: Mon. - Fri. (except holidays), 8:30 a.m. to 5:00 p.m. ET.

2. Forgot my user name and/or password.
To reset your password and/or retrieve your user name:

  • Go to Forgot User Name/Password.
  • Enter the email address you used when you created your account.
  • We’ll send you an email with a link to reset your password (for forgot password) or an email message with your user name (for forgot user name).

3. I cannot log in with my user name/password.
Both the user name and password are case sensitive (i.e., MaryWild is not the same as marywild). It may be easier to use the copy and paste functions to ensure you are using the correct case.

If that’s not the problem, contact Customer Service:

  • Email
  • Phone: 800-227-5558 (US only) or 202-872-4600 (outside the US). Hours: Mon. – Fri. (except holidays), 8:30 a.m. to 5:00 p.m. ET.

4. I used Forgot User name/Password, but I never received an email.
Check your spam filter for a message with the subject line “ACS ID password reset request" or "ACS ID user name request.” You should also enable receipt of messages from donotreply@acs.org.

If that’s not the problem, contact Customer Service:

  • Email
  • Phone: 800-227-5558 (US only) or 202-872-4600 (outside the US). Hours: Mon. – Fri. (except holidays), 8:30 a.m. to 5:00 p.m. ET.

5. Change my email address for my account/ACS ID.

Log in to www.acs.org/editmyprofile. Update your email address, then select "OK" at the bottom of the screen.

What if I can’t access the email address I originally used to register?

7. Format my user name and password.
Your user name and password must be a combination of 4 to 16 characters and may include letters, numbers, and the following special characters: underscore (_), hyphen (-), period (.), and the at symbol (@). They cannot include space(s).

Both the user name and password are case sensitive (i.e., MaryWild is not the same as marywild).

8. Need my ACS member number.
Use our online lookup tool to find your member number. You can also find your member number on your membership card and on the mailing label of your copy of C&EN. It is either the first seven or first eight numbers on your mailing label. The following information helps to determine your membership number:

Seven digits followed by an alphabetical character.
Example:
1234567X.
In this case, drop the alphabetical character at the end and add a zero to the front.
Example:
01234567.

Seven digits followed by a space and several more digits.
Example:
1234567 432.
In this case, enter only the first 7 digits.
Example:
1234567.

Eight digits with no alphabetical characters
In this case, enter all eight digits.
Example:
01343444.
