Cover Letter vs CV: The Difference and When You Need Each
Understand the difference between a cover letter and a CV, when each is required, and how they work together in a Tanzanian job search.
Alexander Phillip
Career Coach and Recruitment Expert
Many job seekers in Tanzania use the words cover letter, CV, and application letter as if they mean the same thing. They do not. Sending the wrong document, or sending only one when the employer asked for both, can cost you an interview.
This guide explains the difference between a cover letter and a CV. It also tells you when each is required and how to make them support each other. If you are ready to create either document, you can write a free cover letter or build a CV with our templates.
What Is a CV?
A CV is a structured list of your education, work experience, skills, and achievements. It is usually two pages for experienced professionals and one page for fresh graduates. Recruiters scan it for facts: where you studied, where you worked, and what you achieved.
In Tanzania, employers often call this a CV, but you may also hear "academic credentials" or "biodata." Keep the format clean and easy to scan.
What Is a Cover Letter?
A cover letter is a short business letter that explains why you want a specific job and why you are a good fit. It is not a repeat of your CV. It selects the most relevant parts of your CV and tells the story behind them.
Think of your CV as evidence and your cover letter as the argument that connects the evidence to the job.
| Feature | CV | Cover letter |
|---|---|---|
| Purpose | List facts about your background. | Explain why you fit this specific role. |
| Length | 1 to 2 pages. | 1 page, 250 to 400 words. |
| Structure | Sections: contact, summary, experience, education, skills. | Letter: salutation, 3 paragraphs, sign-off. |
| When sent | Almost always required. | Required when the advert asks for an application letter. |
| Focus | Your whole career history. | Your most relevant experience for this job. |
When a Job Advert Asks for an "Application Letter"
In Tanzania, some adverts ask for an "application letter." In most private-sector and NGO roles, this means a cover letter. In government roles, it can mean a slightly more formal letter that includes reference lines such as the advert number and post applied for.
If you are unsure, use a formal cover letter and include any reference numbers mentioned in the advert. It is better to include too much information than too little.
How the Two Documents Work Together
Your cover letter should point the recruiter to the most important parts of your CV. For example, if your CV lists three jobs, your cover letter should highlight the one most relevant to this role.
For example
Your CV says: "Sales Assistant, ABC Shop, 2023-2025. Increased monthly sales by 25%."
Your cover letter says: "At ABC Shop, I increased monthly sales by 25% within my first year by building relationships with repeat customers. I want to bring the same approach to your sales team at TBL."
Before you apply, check this
- Read the advert carefully. Note whether it asks for a CV, cover letter, or both.
- Match the file names. Use FirstName_LastName_CV.pdf and FirstName_LastName_Cover_Letter.pdf.
- Use the same contact details. Your phone and email must match on both documents.
- Tailor both. Do not send a generic CV and a tailored letter, or vice versa.

Can I send only a CV? If the advert only asks for a CV, then yes. But adding a short cover letter in the email body can still help, especially for competitive roles.
Should the cover letter repeat the CV? No. The letter should select and explain, not repeat. If the recruiter can get the same information from the CV alone, the letter is wasted space.
Which document should I write first? Write your CV first. Once you know what evidence you have, it is easier to write the letter that presents the strongest proof.
When Each Document Matters More
Some hiring situations rely more on the CV. Others rely more on the letter. Knowing the difference helps you invest your time wisely.
| Situation | Which document matters more | Why |
|---|---|---|
| Large corporate job | CV | HR screens candidates by qualifications and experience first. |
| NGO or mission-driven role | Cover letter | They want to understand your motivation and fit. |
| Government job | Both | Both documents are checked against strict requirements. |
| Referral | Cover letter | The referrer has already vouched for your CV; the letter explains your interest. |
How to Send Both in One Email
When you attach both documents, name them clearly and mention both in the email body. This prevents confusion and shows attention to detail.
Email example
Dear Hiring Manager,
Please find attached my CV and cover letter for the Accountant position at your organization.
I look forward to the opportunity to interview.
Best regards,

Mistakes People Make When Sending Both Documents
Avoid these combination mistakes
- Different contact details. Your phone and email must match on both documents.
- Conflicting dates. Employment dates in the letter should match the CV.
- Wrong file order. Name files so the recruiter knows which is which.
- Generic letter, tailored CV. Both should be customized for the role.

If the advert only asks for a CV, you can send just the CV. However, adding a short cover letter in the email body can help for competitive roles.

In most private-sector and NGO roles in Tanzania, yes. Government roles may expect a more formal application letter with reference lines such as advert number and post applied for.
