Overview

Numbers

Use words for numbers through nine, then numerals for 10 and beyond, generally following AP Stylebook rules. Some limited exceptions and additional guidelines are provided here.

Age

Always use numerals when referring to the age of a person or object. Never spell out any ages.

Do

You must be at least 18 years old.

Don't

You must be at least eighteen.

Currency

Always include commas for values with four digits or more: $2,500. When used in copy, no decimals should be included in a currency value unless the value requires it. Use $25 for twenty-five dollars even, and $25.48 for twenty-five dollars and forty-eight cents. Form fields should always include the decimal ($25.00).

Dates

Spell out the month when writing dates. The day follows the month and does not use cardinal notation such as "st" or "th." There is a comma between the day and the year. For example: August 28, 2016.

Only write dates in numerical format when it's not possible to spell out the month in the space provided. Do not include zeros before single digits. For example: 8/28/2016 or 12/25/2019.

Numerals

You should generally use words for numbers through nine and numerals at 10 and above. However, always use numerals to represent any numerical data in tables or form fields. When the word “one” is serving as an adjective, article or pronoun, spell out the word “one” (i.e. “one of these”). Use en dashes to separate ranges of numbers.

Percentages

Use the percent symbol (%) when indicating percentages in tables, charts, form fields, quotes or otherwise.

Phone Numbers

U.S. phone numbers should be formatted as follows: (555) 555-5555.

Time

Use numerals and capitalized day parts (AM/PM) when writing out a time. For single digit times (1 PM–9 PM), do not use zeros in front of the number. When the time is on the hour (2 PM), do not use zeros.

Time Zones

Times represented on our digital properties reflect the bank footprint of Eastern Time Zone. Include "ET" after times if there will be confusion.
