* Anchor names that contain any character shown in the table on the right will not work as expected. However, any of these characters can be replaced with the "&amp;#" codes shown for them here. Or, the pipe symbol and equals sign can be worked around with {{tl|!}} and {{tl|{{=}}}}, respectively. Markup code such as {{tag|sup|o}} and {{tag|sub|o}} (superscript and subscript) cannot be used. Most other characters, including white space and punctuation, are not a problem.
* Anchor names should be unique on a page, and should not duplicate any heading titles. Duplicate anchors will not work as expected since the <code><nowiki>#location</nowiki></code> links go to the first anchor with that name. Duplicate anchors result in invalid HTML; you can check for duplicate anchors by running the page through the [[W3C Markup Validation Service]].
* If the template is added to a section title then the code will appear in the edit summary window when that section is edited, as in {{nowrap|1="<code><nowiki>/* {{anchor|Issues}}Limitations */ New issue</nowiki></code>"}}. Also, when the section is saved, browsers may not return to the section. Consider using <code><nowiki><span id="..."></span></nowiki></code> directly, rather than using the anchor template, when in a section title.
* Anchor links are case sensitive in some browsers, so treat all anchor links as case sensitive.
